For me: because Chrome is the only browser with worry-free sync.
Firefox's sync for example doesn't sync extension settings, search engines and it fails on Android multiple times per day, with the only solution to logout and login again.

Chrome for Android doesn't support extensions at all, so I'm a bit confused as to how that's a better experience for you.
But Vivaldi doesn't support bookmarklets and I use those a lot.
