Best is highly subjective no matter what the topic. At least qualify exactly what you mean by "best" or else the word is entirely meaningless. What aspects of the browser are important to you? Speed? Rendering? Tabs? Gestures? Some other feature(s)?
If you want to determine what's best for you then take the options for a test drive. You can read all you want but you can't beat first hand experience.
Well I guess I just wanted to get some feedback as to what browser many of you are using here as i am new to the platform. And I thank everyone for their input.
