Yahoo MK vs. Google Analytics

I'm debating to use Yahoo, Google Analytics, or KeyWordMax (#1 rated). We already use their software for tracking (DirectTracks).

So far the major difference I see is that Yahoo is kept current within 5-10 minutes on your bids.

Google has a nice interface but I've heard of problems with the script slowing down pages.

KeywordMax is $200 a month.

I was using BidRank Software. I needed a seperate machine to run it on, and it, like KeyWordMax only updated once per hour. In what increments does Google update?

Yahoo says you can track everyone else (like they all do), but only in 1 hr. increments.

All offer ROI reports so that's equal.

Has anybody had experience with any of these that they would share with me?

I have dozens of seperate campaigns, 500+ affiliate sites and a dozen PPC accounts. I need to manage them all as simply and accurately as possible.

Your opinion?

Thanks in advance!
