What actual complaints do you have about safari? I definitely don't think it's perfect, but Chrome has it's own weird issues and inconsistencies (and is much less efficient on macOS). Chrome is widely chided for its poor memory management.
I occasionally hear “Safari is the new IE”, but as a designer, I could use a little developer education as to what is actually deficient.
I have firefox-specific problems, I have Chrome-specific problems, but I don't remember the last time when Safari caused an issue.

What you meant to say is that testing in Safari is inconvenient for you, so you don't like it. Which is fine, but does not mean that "Safari is terrible".
