Chrome and Opera Mini are also available. I installed them a long time ago, but rarely use either so I cannot say how good or bad they are. I mostly just use Safari. But I'm not a big web surfer using my iPad. I still prefer web surfing on a computer.

I think Chrome supposedly can be configured to sync bookmarks and what not with Chrome on your other devices, so that would be a plus. I'm not a fan of Chrome on the PC or Mac though. I mostly use FireFox on my PC and my Mac and like that I can sync bookmarks. Unfortunately, the FireFox developers have a statement on their website saying they won't be creating a FireFox for iOS.
