To be honest I've not played much of either. Play what you're enjoying but I pretty much only play WoC and try to only play when everyone is human (unless we can't get goalies) it's a much more enjoyable experience. It's not perfect by any means, but the more you take AI out the better the game. Playing AI gets boring fast, you begin to anticipate their movements. It's stale. Humans can make better adjustments OR they can fully blow assignments (not that a computer won't, but it feels much more rewarding when you get a human out of position than it does skating around a cpu) I'd suggest you try that for a bit if you'd like something different.
