Actually DP if you compare their rankings relative to the total number of players, as I kinda commented on before, GT is still ranked much higher than beerz (no offense there beerz, you still a straight up killa

).
So on kills beerz is ranked 4,609 out of (have to eyeball this here as they don't tell you right off) about 800,000 players on the PS3. That puts him in the top 0.58% (4,609/800,000*100) of all PS3 players.
Now GT is ranked about 5,000 out of about 3,000,000 players on the 360. That puts him in the top 0.17% (5,000/3,000,000*100) of all 360 players.
Assuming the quality of players between the 2 consoles is similar (which is probably a fair assumption) beerz equivalent total kills ranking on the 360 would probably be somewhere around 18,000. And GT's on the ps3 would be around 1,400.
So no matter how you look at, GT is without question a force of warfare.
