Opera seems to be pretty smooth. Just need to figure out the bookmarks widget. Bookmarks in Opera do not show up in the bookmarks widgets.
Maybe I can import my opera bookmarks into the stock browser, then they will appear in the widget.
I was a Dolphin user until it got buggy on my DX so I switched to Opera, Dolphin is fixed now but I deleted it and went with Opera as my browser of choice. Dolphin has more options but I've found that I like the simpler Opera layout with the nine item Start menu better. Dolphin also kept opening too many windows on me. Both loaded web pages at about the same pace.
