I play both world at war and modern on ps3. In my opinion people on world at war are bad players, I once got top player for 6 rounds free for all and I even switched hosts twice. Maybe I'm just better in world at war, but I don't consider myself good in either WaW or MW.
How far have you been in Nazi Zombies?
my record is 21 rounds co-op offline w/ brother and no glitches
with glitches I went up to 30
