My opinion only: Your criteria are too vague but also too one dimensional. IE it sounds like you are asking 'which one has the most lumens'...which is not a good way to judge a light.
Also you haven't said if you are shooting suppressed or not, or what environment you will be using it in. Also what your rail length is and what type of rail (m-lok, keymod, etc) would be helpful.
If you are using it in wide open outdoors spaces the amount of 'punch' and how much of a hot spot will matter. If you are planning to use it indoors or in closer proximity the amount of 'spill' will matter.
As for the pressure switch, you asked it like that is the ONLY option. I am a believer that more simple is more better. I do not run night vision so illuminators and all that stuff is not present on my rifles. In other words I have no need to control multiple things such as a white light, a laser, an illuminator and whatever else you can think up. Mine is simply a white light. I put it on the 11 o'clock position (from the shooter's view) so being right handed my left (IE support hand) can activate the light easily without compromising my grip. I run Arisaka lights with momentary buttons on my rifles, and all are the same approximate position. If I need to have constant on I can twist the tail cap 1/4 turn with my support hand and it's on. I've never felt the need to do that though.
I doubt very seriously that my lights are the brightest lumen monsters out there, but where they are located, and how they are activated, as well as the output and spill are all pretty much perfect for me. I am a huge fan of it doesn't have to have wires, then avoid extra wires at all cost. That said a ton of people use wired activation and there is nothing wrong with it just as long as the user has a system for why it is where it's at and all that.
As for wired activation methods the only one out there that even remotely interests me is the Unity Tactical Hot Button. If you want to go that route of wired activation that would be my #1 selection. If I ran a longer rail then the Hot Button would be my first and only choice.
