I use Atlas for speed (it doesn't do much, but it connects fast) and Firefox for add-ons, passwords, and all the other heavy duty stuff I need.
Chrome? Only for a site that won't accept any other browser (yes, there are still people writing websites who don't know what they're doing).
Samsung's stock browser is, AFAIC, a combination of the worst features of all the other browsers out there. It's still on my phone in case someone asks a question about it and I have to run it to figure out the answer.
