I would pick the Plasma.
1. Better blacks (A lot of games and movies are dark, so it can be easier to see whats going on)
2. Bigger screen - 42" vs 37" is still a significant difference and bigger is better when practical with TVs.
3. Better response, less ghosting on fast moving images. You don't see it on movies because they run at 30FPS, but many current generation games like COD IV run at 60FPS with fast changing images.
4. Burn in and product life were problems on very early generation Plasmas.
5. Can display SD images better than LCDs because it isn't a fixed pixel panel like LCDs (IIRC)
Tease.
