This, there is no best browser, they're all fast and have good extensions (except IE offcourse)
It comes down to personal preference. I wouldn't use Chrome even if someone paid me to. I hate the notifications icon that Chrome places as if I was running it on a mobile device and I couldn't find anyway to remove that icon. All I saw on the web is you can hide it but I simply don't want it or don't want notifications from my browser.
So there you go, it is a personal preference.
Me personally, here is what I think:
Fastest in terms of page rendering = Chrome (but I can't use it because I don't like it's interface or notifications icon)
Decent speed, better add-ons, better webpage viewing if you had DPI scaling on 125% and abovfe = Firefox
Opera = What's that? :biggrin:
