It's a great browser and I still have it, but I personally find myself using the stock browser most. Best way to find out is to download and try it out for yourself.
I use it all the time and have no complaints other than flash doesnt seem to work with it but other than that its great. Download it try it out if u dont like it uninstall it.
Used it for a while, along with 4-5 other browsers I had installed but quit. Lightening browser is faster and supports Flash, Firefox supports syncing bookmarks, tabs, passwords and more, along with Flash.
