Just like every OS sucks, every browser sucks too. And by that, I mean none are perfect.
- Chrome has the best syncing and most polish, but its slower than other browsers when opening new tabs and there's no way to get a good new-tab page. You can redirect the new-tab but then the cursor doesn't default to the address bar.
- Firefox has so many extensions, but you have to restart the browser every time you change something and it just isn't as polished as the other browsers imo. I used to love FF, but I used it from version 0.6 til 3.6 and got tired of it.
- Opera, fastest installation of any program I have ever seen. Loads of options, but maybe too many options. Its a little overwhelming and I sort of wish they would focus on just being a browser and not everything under the sun. Very fast operations though. I've never been able to use Opera long-term, its just too different.
- IE9 actually looks very nice and its fast too, but of course its limited to windows (windows 7, maybe Vista?). Basically the opposite of Opera. Its has almost no options and only does web browsing. Not a bad browser at all in my opinion
- Safari? Who cares.
For me, Chrome's sync and polish trumps all others and so I use it for now.
