Quick Version
I currently use a birdcage type flash hider (came with the gun). It is not an A2 and has an open bottom. It's open all the way around except for the tines.

I'd like to try the benefit of a comp or brake. Do I want something like the WarComp Closed-Tine with the ports in the top that keeps the flash-hider function, or do I want a comp with more holes on the top, or do I want more of a muzzle brake device like the Surefire SOCOM muzzle brake?

More detail
I don't have actual experience with muzzle devices other than a birdcage flash hider. Before I go on a muzzle-device safari and build a costly collection of them in a drawer, I'd like to get feedback on the experience of others with 5.56x45 in particular. Because 556 doesn't have a lot of recoil, I anticipate the effects brakes to be subtler but there is still plenty of gas to drive a comp or brake.

I understand there are flash suppressors that cut bright muzzle flash. There are compensators that blow gas up to push the muzzle down, counteracting muzzle rise. And there are muzzle brakes that blow gas to the sides or back to either reduce the gas pushing the rifle backward or possibly even pull the rifle forward against recoil generated when the bullet and powder mass is ejected.

Flash hiders reduce flash that can interfere with the sight picture and cause a more visible signature. Flash isn't desirable, but it isn't an issue in daylight, competition, recreational shooting or most situations where one isn't anticipating return fire.

Compensators should tame muzzle rise. While 556 doesn't generate a lot of recoil, the sight picture is affected. If any magnification is used in the optic, the movement is also magnified. Even slight muzzle movement also requires time for the muzzle to return on target which would increase split times in competition. I imagine that lateral movement compensated by compensators is more disturbing to sight picture than the longitudinal movement straight-back that brakes attenuate.

Muzzle brakes primarily keep the gas ejected from the muzzle from pushing the rifle backward, instead directing it out to the sides. This is understood to be particularly annoying to people adjacent to the shooter's position. While this straight-back gas thrust portion of recoil itself should not disturb sight picture, it is inevitably directed into the shooter who himself does not recoil straight back but bends in his soft tissue and at joints resulting in angular and lateral movement.

I understand that some people find comps and brakes bothersome because of the blast that can be directed toward the shooter. Other people note that the blast is less often directed backward, but more to the sides. There are some brakes that actually direct gas backward. The brakes that direct gas to the sides are more problematic when there are reflective surfaces in those directions.

I also understand there are suppressors, and a lot of muzzle devices are suppressor attachment points.

I currently use a birdcage type flash hider (came with the gun). It is not an A2 and has an open bottom. It's open all the way around except for the tines. My use is for training and civic duty. I have better options for home defense.

I'd like to try the benefit of a comp or brake. Do I want something like the WarComp Closed-Tine with the ports in the top that keeps the flash-hider function, or do I want a comp with more holes on the top, or do I want more of a muzzle brake device like the Surefire SOCOM muzzle brake?
 
Well, you certainly understand the definitions of various types of muzzle devices.
One thing to note is that almost all brakes and comps on the market today are a hybrid of both functions. Even fairly vanilla designs like the old Miculek brake has plenty of compensation designed in.
All that said, I have no idea which one you want. You'll have to tell us I guess.

That’s the quick version for you? lol This is the poster child thread of way overthinking a simple topic. Also some untrue conclusions but not a big deal. And I agree we can’t tell you what you want. Below is my advice for a good all around muzzle device. Pick up one of these and go shoot. Anything you choose will be better than that bird cage thing on there now.

 
It's not intended to be a guessing game. I want to minimize disturbance to the sight picture and keep the muzzle on target. The comp should reduce the lateral motion of the muzzle, but the longitudinal motion that a brake would control does more than just cause the shooter to "feel" recoil. It also moves the shooter who consequently moves the gun. My question is which specific combination of features controls the motion best?
 
A brake does not move the shooter like you state. If it does you need some training. With a brake the rifle will recoil straight back if you are properly behind the rifle. It cuts the recoil impulse and will minimize the sight picture disturbance. That is why people use them in matches. To stay on target.

Alright I'm with Rob now, some overthinking is clearly taking place here.
But in summary, a comp is designed to keep the muzzle from rising, a brake is designed to harness the muzzle blast energy like a sail and pull the rifle forward, lessening recoil. Almost all of such devices on the market today are hybrids and do plenty of both functions.

Actually, I can't think of any pure compensators available specifically for rifles at all. I once installed a PCC comp with only upward facing ports on a rifle, it was uncontrollable how hard it pushed the rifle down. If the gun was full auto I would've been concerned about shooting my feet eventually.

Brakes that shoot perfectly flat for one guy do not for the next, it's a combination of parts configuration, ammo being shot, and stance/biomechanics of the shooter. But mostly the last one.
So about the best we can suggest if you desire the absolute minimum sight picture disturbance is to buy the biggest most aggressive tunable brake you can and tune it to your liking.
 
I guess if you want to minimize the flash and the recoil disrupting the sight picture ( while you’re shooting fast ? ) then either use a comp as the host for your suppressor or use any flash hider and a 20” barrel while using low flash type ammo like TAP JHP ( not soft point ).

This is a misunderstanding. I meant to describe how the longitudinal (straight back) recoil of the gun moves the shooter, and the shooter subsequently moves in directions other than straight back. The brake should reduce all that movement.

Nothing will completely remove that movement. Rifles recoil. Period. It’s up to the shooter to be able to work with the recoil he gets and stay on target best he can. The .223 is not very hard recoiling so it’s not to difficult to use a good brake and stay on target. As Tiger said a compensator by itself would not be what I want on a rifle. Buy a good brake and practice with it. Don’t get into analysis paralysis. If you do this long enough you will try all different types. Buy one that looks good and give it a shot.
 
One of the design features of the AR platform is the axes of bore/buffer tube/buttstock are aligned and recoil goes straight back into the shoulder. Its predecessor, the M14, was extremely difficult to control in full auto mode because the bore axis was above the "axis" of the stock so the muzzle wanted to climb into the sky by the fifth round.

With an AR, there should be no perceptible muzzle rise if the rifle is properly shoulder mounted so the "compensator" piece becomes moot.

OP, listen to Rob. You're overthinking this. Buy a brake with big ol' wide ports and go shoot. Until you've shot many thousands of rounds in something like 3-gun competition, whatever brake you use or don't use is only one of many factors in acquiring and staying on target.
