I'm looking at Compete's new Search Analytics platform that just launched for beta testing and it looks pretty darn good! I can't talk about the details yet though - but overall - you can get keyword referral, site referral or compare 2 sites and get information that's as good as or better than what Hitwise puts out.
I don't think the new platform will be free when it launches - but it seems to me the functionality to run just the reports you need will be present and is built into the platform.
There's still a lot of work they need to do - beta testing stuff - but I'm smiling and I think they are too!
