On what grounds? I'm not sure you've given any reasons at all to ditch google.
They are hiding the 'organic keywords' from viewing, from users who are logged in.
This amount can be from 10 to 25% from all search traffic.
They do this for "privacy" reasons, but somehow, if you PAY them (Google Adowrds), you seem to see all the keywords?
It's like forcing people to use their service.
