Yandex does look fast. UC Browser is pretty good too. Its more integrated and has better features than chrome.
I do like the main Browsers but I think that dolphin browser on an android phone has been my favorite browser to date. I also like the badoink app that can be used as a web browser. I liked that I could easily download videos with badoink no matter what site I was on. Dolphin browser on the other hand has been the smoothest browser that I have ever used on a small screen.
