Personally, I like Chrome's address bar better than Firefox 4's. In Chrome, I can type g-m-<enter> to go to Gmail. In Firefox, it's g-m-<down>-<enter>. It's a little thing, but it makes a difference to me.
Can't live without Tree Style Tabs though. Firefox is my "heavy lifting" browser.
You can change FF's behavior to match Chrome: setting browser.urlbar.autoFill to true in about:config will enable inline autocomplete in the awesomebar, instead of having to arrow down or tab down.
The solution I use is bookmarking sites and aliasing keywords to the bookmark - right click on a bookmark, go to properties, and add a keyword. For example, I have "hn" as the keyword for the Hacker News homepage, so if I type "hn" and hit enter, it expands to the full URL and goes to the page.

This is really easy to do in Firefox with keyword bookmarks[0]. In fact, this is one of the things I hate about Chrome - keyword bookmarks are a total hack (you have to create a search engine without the %s, for string substitution).
