The only thing Firefox is faster than is IE I believe. I've tried a few Chrome betas, but it's nearly impossible to tell what version you're running versus what's newly available - one of the many things I can't stand about Google software and web pages. I've found it decent in terms of speed, probably second only to Safari on both Mac OS and Windows. More recently testing Mac OS versions though. I still keep a copy of the more popular browsers on a virtualized Windows installation for testing, but I haven't updated to the latest betas there yet.
