I am looking at Skyfire, Opera Mobile, and xScope Browser.
I tried Skyfire once, didn't like. Never tried xScope.
Opera Mobile has GPU acceleration, which makes scrolling and zooming MUCH smoother than other browsers, especially on desktop formatted pages (which is primarily what I use it for). The interface is okay. I prefer Dolphin HD but Opera's UI doesn't get in the way too much.
I tried Dolphin HD but I dont like theirr tab interface.
Really? That and the menu pullout gestures are some of the best things about it for me.
