Used to be Dolphin HD, but once I tried Chrome I was hooked. Used it for a few days and I don't miss Dolphin at all.
You can still keep the stock browser and Dolphin around to try out, but I find myself pretty much just using Chrome.
Chrome indeed.
Flash or not, Adobe already dropped support and it'll eventually go the way of the Dodo.
I am surprised no one has mentioned maxthon, works well for me.
