Firefox's ability to transparently sync tabs between all your devices is useful but it's not up to speed with Safari's -- sometimes it takes MINUTES for it to sync.

I'd argue with you about what a "real" browser is all day but really, it boils down to -- I am not interested if the latest standards are implemented. Those latest standards are made by regular humans, and they do dumb crap all the time. So "newest" =/= "best".

I quite like Safari's Reading mode and Reading list (especially having in mind that it can cache offline things you put in the reading list; you can read all of those without internet).

I will concede however that it's definitely very behind in terms of addons. That's a weak point. And Firefox gets better and quicker constantly.

TL;DR: I use both Safari and Firefox heavily and I love both. But Safari is little better in terms of information management.
