Which one is the fastest in your opinion? I think kiwi is still slightly faster than this Samsung browser, at a higher battery cost obviously. Regards the plug in, yes I know but it appears in the app drawer as a stand alone app (you just modify the settings ).
It definitely seems to consume less battery than kiwi thought.n
Via Browser is the smallest file size browser at the moment with only 1.5 MB.
It make use of the built-in app Android System WebView to achieve small app size.
Personally didn't try it, so no sure how fast it will be.
Kiwi browser has an update recently, so you may also try update it.
