1. Smoothness. Must have hardware acceleration enabled. I find that UC Browser HD is good in this section.
2. Has good HTML5 support (tested from html5test.com). I find Dolphin has the best.
4. Supports gestures.
5. Supports proper fonts as set by site. For example UC Browser uses system fonts and it sucks..
6. Supports flash.
From my findings so far with Exynos (P600):
UC Browser is the smoothest because of hardware acceleration, has gestures, has flash, html5 support is good but not good at rendering fonts.
Dolphin with jetpack is close in smoothness but swiping up and down is too fast and the page goes to its top or bottom by a slight touch. Has the best html5 support and the gestures are not so great as UC.
Chrome beta is a bit behind in smoothness, great html5 score but lacks in gestures and no flash. I don't even discuss Chrome (plain), it is very jerky.
Firefox is a big dissapointment. I think however that Note 3 is great with firefox. I need some opinions from the Note 10.1 2014 Snapdragon users for Firefox (P601, P605).
Maxthon sucks bigtime. Your opinions please and if there is a dev that can suggest a speedup for a browser is welcome.
PS: I use a SM-P600 and have CleanRom and Bindroid kernel.
