You will hear advocates of Firefox spout rhetoric.
You will see IE fanboys split hairs to ensure that they can say that it isn't IE's fault.
One thing you won't hear most of the time? A peep from the folks who wisely use
Opera.
Not Safari, not IE, not Firefox, not OffByOne, not Netscape, not Maxthon, not any...
You will not find a browser that is, in and of itself, more adept at rendering markup properly. You will not find one with fewer exploits and that large a footprint across the globe. You will not find one that is simpler and easier to configure because, really, they all do the same things.
See a feature in a browser you like? Chances are it came in Opera first. It is not my default - it could easily be though.
