I enjoyed Safari for about an hour in Lion (because of the gestures, and how they broke in Chrome), and then immediately went right back to Chrome. Apple's done a lot to improve Safari over the years (especially recently), but it's still not close to where it needs to be for everyday browsing. Development is pretty equal, although I'll always find myself using Chrome over it because of Chrome's much, much faster release schedule of improvements to Webkit's tools. Safari gets them... eventually. Eventually isn't good enough these days, when entire new pieces of technology appear in the span of months.
For regular browsing, I can't stand not having:
* Favicons on the tabs. It's impossible to glance at 5+ tabs in Safari without getting completely lost.
* Favicons on the bookmarks bar. My bookmarks bar doesn't have a single character on it, it's all just favicons with blank names that makes it into a horizontal list of frequently used sites.
* Any sort of Synching. Right now my Chromes at Work, Home Desktop, Laptop, and Tablet are completely in-tune with each other.
* A real omnibar/awesomebar. There are some extensions that make this more bearable, but the default address and search bars are pretty worthless.
