The main problem with Plasma is pixel burn. Static images makes them stay forever (for example, you put a completely black background, and you have an image of a person with pixel burn, you will see a little trace of it in the black background and everything).
If you are gaming plasmas are bad in general. Panasonic recommends you do not game on a plasma. Not to mention they create a hell of a lot of heat, so unless you are in a big open room they are terrible in terms of comfort. Also may I remind you guys plasma refresh rate is WAY different that LCD refresh rate, 600hz on a plasma is the same as 60hz on an LCD/LED.
you are only going to be using plasma on larger screens, and generally you need to be 3 or more metres away from a 42". so unless you squeezed yourself into a room with a massive plasma, heat should hardly be an issue
btw, 600hz isn't even necessary on a plasma.

i don't see why plasma's would be bad for gaming either. used my pc with both a 42" plasma and a 37" lcd (pioneer and sony bravia respectively), and have to say that i preferred the plasma
LCDs are lit from an array of cathode tubes from the back - LEDs are lit from (as the name suggests) LEDs.
the main advantage to this is no SCREEN-BURN from over-contrasting. i went through 5 LCD TVs because of burning, before i opted in for LED TVs and MONITORS.
LEDs take less time to cool-down to an off-position (BLACK), giving better contrast ratios from high-whites -> pitch-black in less time (without bleeding). the phosphorus in the LCD backlit tubing takes time to react, whereas LED nodes do not. this is yet another reason why LED monitors have a faster response time (<=2ms)
they are the way forward IMO.
