...No one!
-I love the way that OmniWeb it lets you surf and view pages but it is incopatible in some sites...
-Internet Explorer is the most compatible browser (yes I know its from M$ but that doesn't change the fact that it is the MOST compatible browser on Mac) but at the same time is not the fastest or the most beatiful while reading those sites...
-Chimera is simply put "SPEED DEMON"... Hell, in many sites beats even PC browsing by far!!!
-Mozilla is somewhat between Chimera and IE! Compatible and fast that is
-Netscape well, if you like heavy stuff without actually earn something this is it! However, I would chose Chimera or Mozilla ANY DAY over this bloated stuff...
-iCab, as Ed said before, can actually deliver but TOO many preferences to deal with...
-Opera... This one seems to be a cross between OmniWeb and Chimera: Too fast, too nice to view sites with and not THAT incompatible with the majority of sites... Yes, it crashes a lot and has redrawing problems but it is BETA or should I say ALPHA?
Well, the above are my experiences and the ones I use are (and yes with that order):
-OmniWeb
-Chimera
-Opera
-Mozilla
-Internet Explorer
-iCab
-Netscape
What can I say? OmniWeb is more than enough but damn those Tabs and Speed of Chimera! Opera et al I use them just for testing reasons
As for PC browsing I use 99% Mozilla and Opera... Internet Explorer is too much of unstable for me (supposedly it doesn't crush but most of the time when a site isn't responding 99% you have to terminate the app and restart it) not to mention the inability to block popup windows, no Tabs to be found and TOO many security issues scare the sheet(!) out of me
