I'm in Israel where our internet providers are quite crap and I do pretty **** well on MW3. I suppose I'm not terribly whiny about my ping after so many years gaming but who knows. At any rate, the p2p networking model from MW3 seemed to work pretty well. I have seen that the XBOX players are having lots of issues. Hopefully Ubi does something to address that. It may either be users' network settings which they should put out a bulletin about or it's an issue in the netcode.
