i'm regular user of Dolphin Browser. Recently i've heard that there is a Galaxy Browser, and then i give it a shot.
unlike Dolphin, it has ads but you can purchase Galaxy Browser Pro without ads from Google Play. Dolphin is a free app without ads, that rocks.
However, it's very convenient to switch a webpage between desktop mode and mobile mode. All you have to do is check or uncheck Request desktop in the side bar and i like this feature better than that of Dolphin.
