Should I buy Halo 1 on the disc or download it on Xbox Live?

I'll be doing lan parties, and also the same for Killzone 1. Should I buy Killzone 1 on the disc or buy it on PSN? I want these two games to have the best graphics they can, so they will look nice on my HDTV.
I'm going to buy Halo CEA, but only for the single player on Live. It's just Reach multiplayer, so I'll just buy Reach for that, just like I'ma buy Halo 3: ODST, just for 4 player firefight.

You should wait and buy the Anniversary edition in November.

I'd say get it on XBL. I think if you get the disc it will not fill up your entire HDTV.
As for Killzone I'm not sure.
