I usually use Opera Mobile, because it's my standard desktop browser and I can easily get my favorites by syncing via Opera Link.
Normally I'm not a real fan of commercial closed-source software, but Opera made my day pretty often
svg rendering and image quality is not 100% in Opera Mobile. QQ browser is the best for any Android phone but has no bookmark backup or cloud option. Firefox has wap and mobile site page fix problem. Miren browser is not a full fledged stand alone browser, it works on stock browser. Dolphin also has a few bugs. UCmobile gets freezed or FC after multiple tabs open. Boat browser is somewhat true android experience and friendly with not so much data compression. Boat browser handles payment gateways and java scripts well. Maxthon browser is also quite sturdy and reliable to use. Puffin browser is an excellent browser with full page performance but starts with the homepage with new window or tab. Ninesky browser too is very descriptive but has noticable bugs.
Normally a browser's credit is noticed while loading a media rich heavy website and when multiple tabs are open upto 10.
