Stock browser seems to work just fine for me. Full screen + quick controls are sweet. I tried Dolphin when I first got the phone but it kept FCing so I uninstalled it. I tried ICS Browser+ for a bit but it was a tad buggy and the quick controls were a tad overwhelming, didn't really feel the need for that many on the screen (plus the little exclamation mark icon instead of the three dots icon was annoying me).
I have Opera installed in case of any reason I may need it (slow connections, etc.)
