Figured I would chime in, mainly because I've got a slightly different thought. I actually prefer Dolphin Mini. I find its very fast, easy to use, and has a nice collection of options. The "speed dial" it opens to makes my browsing experience great. I've dabbled with Dolphin HD, and its certainly a great browser, but I found I didn't need a lot of the extra bells and whistles built in.
In my use, i was also a fan of Opera Mini but something about the overall layout didn't appeal to me. Certainly also a great browser option as well.
Any questions, let me know
