The folks over at Macintalk has done the dirty work for us, putting four major browsers to the test on Mac OS X (although, they disregard Opera completely.) They looked at things such as speed of rendering, RAM usage, Javascript loading, standards compliance, and even RSS handling. Reading through, I must say it is pretty thorough. If you have been wondering if paying for OmniWeb would give you a batter browsing experience on the Mac than sticking with the free Safari, Firefox, or Camino, give this one a read.
