I have opera mobile, firefox 4 beta2, stock browser, skyfire on right now. some thoughts
1. speed and snappy-ness: Opera mobile>skyfire=firefox>>stock browser
2. flash video: stock browser and skyfire only
3. syncing across the devices and computers: firefox>opera mobile>>rest
4. the font: stock>firefox>opera mobile=skyfire
5. image quality (when zooming in): stock=opera mobile=skyfire>firefox
I especially like the awesome screen of firefox, it just makes surfing so much faster.
One thing about opera mobile is that in portrait mode, it always try to render at a width of 768px, so it won't shrank down enough to fit the screen width.
