ExtremeTech is running the sort of round-up article I've been waiting to see: Opera 9 vs. Firefox 2 vs. Internet Explorer 7. While the latter two are both in beta, ExtremeTech gives them all a thorough go-'round. The review also includes some revealing benchmarks, testing their memory usage with and without a bunch of open tabs (spoiler: IE wins with one tab, Opera wins with a bunch) as well as their start-up time (Opera is the best, and Firefox is the worst by a wide margin) and Acid2 standards test performance (Opera). ExtremeTech gives all three browsers high marks and doesn't declare a "winner": Firefox wins points for security and extensibility, Opera impresses with its mature tab implementation, and IE7 seems to have done quite a lot of catching up.
