The companies all claim they fixed the plasma burn issue in their newer models but I've sold HDTV's for a year or so and I learned a lot about them during that time. It might be true they fixed it, but my instincts would tell me to go LCD. I'm suspicious like that. 
For response time, 5ms sounds good for a mmorpg, but might still be a little slow for a shooter. Good LCD compy monitors have a response time of 2ms, so that gives you an idea.
Anyways! The OP said he was going for a 32" and those don't come in Plasma, for most companies. (Plasma technology is expensive so only worth the monies on bigger models).
If you want to go with BestBuy a quick look at their available 32", along with my general (yet slightly outdated) knowledge of the companies that make them tell me the following:
Insignia and Dynex: I haven't ever heard of those until now. Their websites are strangely similar and both of them are exclusively available at BestBuy and FutureShop (which is essentially the same thing as it's all owned by the same guy). Sounds like it is to TV's what President's Choice is to groceries. I wouldn't touch those TV's with a ten foot pole. >.>
LG: Our store doubled up as a Service Center. It was full of LG's waiting to be repaired. Bad Chinese TV's!
Toshiba: That's the affordable decent level of Japanese TV. What that means is it's Good (but maybe not as good as other Japanese models), Affordable (the only thing we had that was cheaper was Samsung) and Reliable (it -is- Japanese, that means it's not made out of crap).
Sony: Possibly better image than Toshiba but equivalent models will usually be significantly more expensive on the Sony side. Usually for no real good reason. It does have the usual Japanese reliability.
Panasonic: On equivalent models, more expensive except that unlike Sony, they actually have a reason for that. The reason is superior service if something breaks. This may or may not matter to you cause it has the Japanese reliability.
