iOS Web Browser Opinions

I think Brave is the best third party browser, unless you need accessibility. Just use adguard, wipr, or next DNS with Safari.

Again, unless you're in the eu literally browser have to use webkit for rendering so the only thing that will change is the sync of data and minor ui change. The accessibility experience is 100% the same.

safari is a dream on ios, the few shortcomings it has are due to the touch interface and not due to any issues it has... for the mostpart anyway

I'd say that safari is indeed a dream on ios compared to macos, the key thing being that it's a touch interface :)

Using one browser or another on iOS is the same thing since they all have to rely on Safari's WebKit.
Here In Europe, where Apple is forced to listen to users at least a little, there are no differences because, for now, there are no browsers using different WebKits.
That said, Safari is a good browser.
Okay, it's not comparable to Firefox or Chrome on desktop—that's a whole different world—but for everyday use, it's still a solid choice.
There's also the Orion Browser, which allows installing Chrome or Firefox extensions, but aside from the fact that it only works with very simple ones, I wouldn't recommend it since its interface doesn’t work well with VoiceOver.
