Better browser will be hard to define, browsers have more to them than strictly performances, chrome has become one of my least favorite browser, while I love opera (which I think is based off chromium) because of simple things that add values:
Better general browsing performances on it (which I don't understand, it just works better for a general purpose on my devices)
Lock the desktop user-agent in the parameters rather than for a single tab (mobile versions on a tab? No, I want the internet, not the reduced version filled with fullscreen/autoredirect irrelevant ads, go learn to make responsives websites based on the screen size and don't limit me because of what OS I use!)
Save pages for later (may be present in others but it is just more convenient in this one).
I choose the browser interface, me, not somekind of screen size check.)
It may not be possible to enable webGL in it, but a browser must browse first.
So hard to défine a better browser, even though spec compliance is important, we all know that as long as browsers won't be perfect, people will try to sniff them anyway, ruinning the whole point of having specs.
