I've been defaulting to Opera more and more these days because, strangely, it seems to be the most stable for me these days. I say strangely because of course most sites don't even test for Opera, but I often have trouble with Google properties in both Firefox and Chrome. On my old, slow desktop Opera and IE are way faster than FF and Chrome. I expect that's because of some sort of conflict or problem with the JS engine who knows, but even with all the plugins off, Firefox bogs down all the time (on the laptop, all browsers are fast and stable) and Chrome tends to be unusable even on Google properties.
I haven't quite gone to OPera as my default browser, but I do think the clunky feel I used to dislike has given way to a far less clunky feel than Firefox, currently the clunkiest feeling browser on the market.
Firefox is a great tool, though - Firebug is still awesome, HTTP Live Headers, Tamper Data, Web Developer are all handy.
