Noted Windows review site Tom's Hardware recently reviewed the latest versions of some of leading web browsers running on Mac OS X and Windows 7 and found that, overall, Mac browsers -- particularly the one judged the best overall, Safari (v5.1) -- were catching up and in a few cases exceeding the Windows browsers, particularly with page load times, Flash, HTML5 and WebGL. Google's Chrome was judged the best overall for Windows and a stiff competitor on OS X as well.
