I downloaded Chrome and didn't notice anything significantly different than Safari (other than the strange-looking tabs, from the standpoint of someone used to Safari), so I shrugged my shoulders and deleted it.
I'm not saying Safari is a superior browser. Just that it has always seemed perfectly fine to me.
On an unrelated note, firefox on mac is a really sorry case. I hope this is not only on my system.
One plus to Chrome is the integrated search/URL bar, also. I've gotten so use to using the same bar for both, that I've had issues using other browsers when they try to visit some site that's actually my search query.
Firefox still has a place on my system, but it's definitely not something I want to use all the time.
