Choosing the best browser is difficult as there are many variables that may be better for some and worse for others, it all depends on what you really need.
If you want a browser that runs Flash videos, surely your choice is Skyfire (one of its immediate negatives is that it pays for $ 2.99). If you want a browser that doesn't consume much of your internet data plan, then your choice should be Opera Mini. If you want a browser that has different features like gesture recognition and sound system, your choice should be Dolphin. But if you value a fast, effective and simple browser, your choice will be between Chrome or Maxthon.
One point that should also be considered when choosing is the compatibility of desktop browsers with mobile browsers. And here who takes advantage is Chrome.
