Same here; I don't know if I've ever seen a site that works in Chrome but not Safari (I don't doubt they exist, I just don't tend to come across them).
As a MacOS Safari 12 user, I've recently come across several important sites where some functionality fails hard in Safari yet works in Chrome ie barclays.co.uk and easyjet.com
I don't have any proof but my suspicion is that I've seen more sites failing Safari since Mojave.
I really dislike (& distrust!) using Chrome now, especially for e-commerce sites or anything with SMS based 2FA as Safari's ability to pull codes automatically from messages is a godsend.
