My 50' Hitachi Plasma lagged like crazy when I played Halo 3 on it. I switched over to my room TV a 32' VIZIO LCD and experience very minimal to no lag and it really helped my game play as you could imagine. I got as low a 25 in team slayer on the Plasma but when I switched over I got back up to a 40 in no time at all and I was putting up huge numbers immediately after switching, so i know it was not any newly found skill. So LCD won me over for what type of TV to game on.
However, the picture on the Plasma blows my Vizio out of the water obviously. I just wouldnt recommend a large Plasma for gaming the lag was extremely frustrating.
