I use Chrome, it seems decent. Clean interface, fast. I speeded it up considerably by changing those default tiles to 512..
Chrome used to be dog slow, but now it's one of the fastest mobile browsers on the market.
Issue is it's severely lacking in feature set, and I really don't want Google to be storing anything and it is always trying to get you to sign in (and signing out is as confusing as ever now... not hard, just confusing).
Need Save Offline, Reader Mode, Independent Brightness Control, and a way to tell the Browser to Download to the SD Card's Download directory instead of internally on the phone...
So I disabled it.
They also made some baffling UI changes. They bury the Forward and Back Buttons, for example, which makes it an absolute PITA to use compared to the Samsung Browser, which I prefer for its features and layout.
Chrome is the more responsive UI, though that may change after the next major update (on my Note 3). It's not the performance, it's Samsung's Animations that seem to make their browser seem... sluggish... for some reason (too slow, almost makes you think closing a tab takes more than one tap sometimes).
