Multi touch for back and forward works just fine (though the animation isn't as nice), but there's no support for pinch-to-zoom. Kind of a deal-breaker for me. No native support for something similar to the "Reader" feature as well. The only thing that's currently better about Chrome is that it gives each tab its own system process, so if one tab crashes it doesn't kill the whole browser like with Safari. When OS X Mavericks is released Safari is going to be one process per tab too, so at that point it will unquestionably be the superior browser on Mac.
You might as well just start transitioning to Safari now. That's what I'm doing. Mavericks is right around the corner!
