Rainbow six vegas vs gears of war   stance: rainbow six is far superior !:
I actually think GRAW on the 360 is the best military multi player game on the system.
The graphics are actually superb and obviously more realistic (being based in a much mearer future with less technological assumptions made).
The game play is completely engrossing and presents a fairly open playing feild to noobies alongside more experienced players.
The interface has been deisgned with a classic FPS style with only a few additional changes which means you aren't distracted from the game by trying to remember which button to toggle etc.
And GOW was simply over hyped and doesn't present the same replay value to me that GRAW does.
