720p Versus 1080p HDTVs. The Facts

[GalacticPenguin]

Ok, so i am in the market for a HDTV.

The main purpose of the TV would be for Blu ray movies and PS3 games, like Final Fantasy and things of the sort.

I watched Final Fantasy 7 Advent Children Complete on my parents 50+inch HDTV, i think it was a LCD and it looked beautiful. I watched it in 720 because my friend said that 1080i was actually worse than 720p. Something about how 1080i was = 550p or something of the sort. Anyway i have been looking around to see if the difference in 720 and 1080p is truly noticeable and worth the money. I always hear both sides of it and just need someone to shoot me straight so i don't waste my money on a T.V. It would be a tv i would take to college with me in the dorm. As far as money goes, i am willing to save up to high amounts. My first instinct would say get the 1080p, but some would argue otherwise.

Also what are the best brands/ Type of T.V. to go if i am wanting it to last a long time and get the most out of my PS3
