I won't make a blog-post detailing things, since you could just as well google your way into those details. Instead I'll note down:

- Best devtools, particularity regarding how the tools feel to browse around in.

- Feels slightly better to browse with. Only small differences, like how scroll is just a bit "smooth".

- Looks better ui-wise. (arguably a personal take, but also arguably not)

- (as others will note) Because it's essentially standard at this point, and I work with webdev.

I use chromium though, at least it makes things less google-y. And I thoroughly dislike the Alphabet-monopoly situation and all the bad things it brings. I really wish browsers were far less centralized than they are right now, and that some kind of web-standards consortium worked better than it does. But I don't pretend to be able to fix things like that right now. Besides, at this point, the whole Alphabet-monopoly situation is arguably a political issue rather than a technical one. (Political issues require political solutions)
