Chrome is worse than Firefox only because of extensions (and a couple of other minor things...full page zooming, for instance - which is in the latest beta).
Almost anything is better than IE 7.
If they can port the extensions from FireFox to Chrome - I'll be there.
I've got no idea if that's even possible, but it might be. Chrome is a hopped up version of webkit (I'm just guess this - I've not had a chance to really play around with either of chrome or webkit)
