Can’t see a picture but I think I know which you mean as Kuba has both variants in the gym.
I wouldn’t be so fixated on loading if your goal is to build muscle, but more in the stimulus of the target muscle whilst lifting safely.
For me, neutral grip is perfect as I’m quite narrow and it just feels a lot nicer on the elbows and shoulders. I can lift about 10kg per side heavier using prone grip but it feels less safe for me.
