I use Gamespot - have for years. If I want info on a new game or upcoming titles that's where I go
Check out www.lensoftruth.com they do direct comparisons on most new releases and go way in depth with their comparisons.
I've used http://www.vgreleases.com/ for ages I find it does the trick.
It tracks releases in all regions and they seem to keep it very up to date. All release dates are backed up with their sources.
They generally do estimate release dates on future titles but update them as more info is released.
Very handy site to see what comes out on which platform and when.
Oh the site also forms part of the N4G network.
It tends to be xbox graphics are a bit better then the ps3 since its really difficult to develop for ps3 the cell processor is a very complicated peice of hardware devs cant seem to get right. But the ps3 exclusives are toooo sick. Nauthy dog seems like the only studio to get the ps3 right.
Metacritic?
Do a search for the game in question, and you'll see average scores of the game on each of the platforms that game was released on, as well as a range of reviews.

wont the comparison sites just be fanboy bias?
