A plasma is better for anything fast action (less blurring/faster refresh rate). For a LCD you want at least 120hz (240 hz is way better) and your viewing angles are limited. Plasma tvs do suck a little more juice, but nothing you can notice, but they run hotter. You also need to think about glare (sun or ambient light). Plasmas have a glass screen that is highly reflective while LCD has a mat screen.
Plasma=best picture (with the right lighting conditions) and cheaper, but slightly less screen life
LCD=Great picture (within the correct viewing angles) and slightly longer screen life, but more expensive
Go all out. Get a projector with stadium seating
