Welcome!
If you can, test out the trigger pull. Especially, pulling slowly in SA.
Triggers seem to be variable, I would pick the one with the least amount of camming/grittiness.
Also, look at the breach face of both for rough edges, especially at/opposite of the extractor and at the firing pin hole.
While you are at it, you can compare ejectors. Some come from the factory with a nice smooth bevel, others are square and rough.
The nicest factory trigger on any of my CZ's happened to be a '14 75B. It also happened to have a nicely smoothed bevel on the extractor.
