What happens if you mix r134a and r1234yf?

If you were to put R1234yf in a system designed for R134a, it looks like you’d end up with about a 10% loss of cooling capacity, but putting R134a into a R1234yf system would be a wash. It appears R1234yf oil is compatible with R134a (but not vice-versa), so shouldn’t be a problem there.

Why is r1234yf preferred over r134a?
