The benefit of R1234yf is simple. The new refrigerant lasts only 11 days in the atmosphere compared to 13 years for R134a. This is why the EPA is requiring R1234yf to be installed in all new systems by 2021. The European Union required the changeover on Jan. 1, 2017.

It is not a question of if, but when your shop will have to deal with one of these systems.
