Not a lot of detailed comparisons between the 2 (that aren't written by the companies in question)
I tried migrating to YB at one point. I had issues migrating the indices (got lots of timeout issues). Once I got past that, I found out that a particular query I needed to do didn't have predicate pushdowns implemented and so always resulted in a full table scan. Ended up giving up.
Cockroach (at the time at least, ~1.25 years ago) didn't have support for some JSONB things that I needed.
I don't think we trialed YugaByte at the time because an ORM story was a dealbreaker and CRDB at least advertised support.
