Since my S2 days, I've always been pretty much a stock browser kinda fella. I would try the others out briefly, but always end up back on stock. On the S4 however, I've been using a mixture of stock and Chrome, with probably Chrome edging it for me. That was before I put on Dolphin Browser Beta. Now I'm not sure what has been added/improved in this Beta version, as I'm not overly familiar with it, but for me this is head and shoulders above the others I've tried. Great to be able to do pre-defined gestures to open up specific bookmarks, and the scrolling. WOW! Its smoother than anything I've seen on ANY device. I wish all scrolling throughout the entire S4 (menus etc) was as smooth as this. If you have not done so yet, give it a go. You won't be disappointed.
