There are two shock wave areas in propeller.

Right, as a function of angle of attack and not diameter....
You are getting into the weeds without keeping an eye on the big picture. Propeller designers are aware of of this and design accordingly. It is too easy to spot a bad propeller design very early on.
It is a general principle that smaller diameter is better for Vmax performance.
Keep the discussion to diameter effects.....
Take a lesson from Professor Von KlipTip.....

6. What is the importance
of propeller diameter?
Ideally, the propeller diameter should be
greater for efficient low airspeed operation
and smaller for high airspeeds.
