Never used a magpul but really a fan of the Bravo for the 10/22 platform, loved it for the rem 700.
The Bravo's weak spot for the 10/22 is It only uses two narrow bars to "clamp" to the main chassis that the action screw bolts to. It doesn't make a very secure interface, multiple people have reported being able to "nudge" the barrel off center and have it stay off center and go back the other way etc. Mine had quite a bit of wiggle room at the rear of the action. Now with a Supergrade if you have the rear attachment that certainly will help. I ended up putting a beater 10/22 in mine and bedding the heck out of it, which it's rock solid now.
I also wasn't a fan that there's a gap inside the magwell between the plastic overmold and the metal interior chassis skeleton and I frequently had mags hang up on it when inserting them. Ended up fixing it by epoxying to take up the gaps, never had an issue again.
For Non-Kidd users there's also no option like some other chassis have (MDT/Oryx, Titan, etc.) that holds the rear of the action.
Plus is that the cost is very low, as long as you don't do the upgrades, and the rest of the chassis is quite good. If you want a spigot mount, and tooless LOP and buttplate adjustment the price quickly approaches $500. You can of course spend more Woox you can drop $1000 on one. From all the ones I've seen I think PDC custom impresses me the most but it's also not cheap.
That said the 10/22 has to be a horrible platform to make a chassis for, just due to all the tolerance/size differences and keeping a low price point.
