A week ago I said I'd try Google Chrome for Mac out for 1 week as my primary browser.

I'm sold.

Chrome is faster than Safari, doesn't nag me with add-on updates like Firefox and has a great set of innovative UI conventions.

The only complaints I have:

1. There's no indication in the address bar if a page has an RSS feed
2. Bookmarks in the bookmark bar aren't compact enough, I felt I had to cull out a lot of my frequently visited sites

So, I'm keeping Chrome as my primary browser for the foreseeable future.
