Exactly - the fact that Google actually pays attention to you is a nice plus. If I had an issue with a campaign, I had a direct phone number for someone who could fix things.

That said, at that point, support had already started to go downhill & we found the "reps" usually knew very little / less than us about campaigns. Interestingly enough, we found that BING reps were much more helpful as they were eagerly trying to make up market share.

[EDIT]: You also get access to betas & other google "tests" they're running with adwords that most normal advertisers don't. Most of them are designed to make Google more money, but every once in a while they'd come up with some cool stuff that'd be really helpful.
