Lcd or Plasma best for gaming ?

 Hi, I still can't decide which TV to buy, Panasonic 42pz70 or Toshiba 40xf355.

For now I'm watching SkySd but plan to get SkyHD soon, I've also got a PS3 and watch quite a lot of Blu-ray.

I think i'm leaning more towards the Panasonic but people have told me that Lcd is better for gaming and I'am partial to a bit of online gaming. What do you guys think ?

Thanks
