Firefox has been improving noticeably faster since Chrome came into the picture. Not just lately either. FF has gotten much faster, much less memory hungry, and added a lot of new features (many inspired by chrome).
I find I use both regularly, and which I use by default changes often, depending on the circumstance. E.g. they're both pretty fast these days, but on different things. FF seems more memory efficient overall, but chrome's per-tab-process thing makes it easier to manually reclaim memory by closing a tab (the per-tab-process also probably makes chrome less able to share memory between tabs, so there seems an inherent tradeoff, and explains FF's win here).
So it seems a virtuous cycle, and chrome's to be lauded not only for a great browser, but for heating up the browser race in a way that seems to have resulted in every browser improving.
I just added fauxbar[0] to chrome, which fixes the worse feature of chrome - the bad history integration when typing in the url bar. I love both, too, but this addition to chrome puts it back in the lead.
