If anything chrome is the engine with odd quirks you are forced to work around.

I haven't found this to be the case in my experience.

Maybe it's just iframes that are the issue but they were a devil and a half to get working in chrome (or blink ig) without relying on third party cookies.

Interested in what you are doing with the iframes. Something with complex authentication? I've been forced to use iframes a few times for 3rd party resources that should have been first-party (mostly with banks and credit unions), and have only had some styling issues on mobile (which have been overcome by using JavaScript and window.matchMedia to check for media queries).

Chrome's quirks become the standard and other browsers have to implement them.

Back fifteen years ago IE held back the web because web developers had to cater to its outdated technology stack. “Best viewed with IE” and all that. But do you ever see a “Best viewed with Safari” notice? No, you don’t. Another browser takes that special place in web developers’ hearts and minds.

Yes, Safari is not exactly like IE because IE had a dominant user share once upon a time.

We don't see "best viewed in Safari", but we do see plenty of sites that can be viewed in Safari, despite the extra effort used to get them there. And I'm not even a regular chrome user.

The absolute vast majority of web sites require no effort to "get there".

The absolute vast majority of those which don't work in Safari use Chrome-only non-standards.

And there is a tiny minority of sites that run into some Safari-specific quirks
