Right now I've found Atomic to be the one I want to use when doing fairly standard web browsing, by which I mean lots of reading, sometimes with multiple tabs. I do get the text-entry bug sometimes (the one where it forgets it's in text mode), but closing the keyboard and retapping the field fixes that for now. It's generally remained the most usable for me and my browsing habits. But icab does have one advantage, the black and white module. This makes browsing forums where you want to uncover "spoiler tags" much easier.
Meanwhile, a very few sites only seem to operate right in safari, so I'm basically stuck with all three.
