The privacy stuff alone is making me want to use it over Firefox.
Firefox 3.1 beta 2 has a private browsing mode (although it's not as convenient as Chrome's, you have to convert your entire session over to it). I've been using it as my regular browser and have never had a crash or anything, actually I can barely distinguish it from 3.0.
actually though, if you don't use add-ons, why aren't you using Chrome?
