I could but Rookies believes what Rookies wants to believe
Joking aside the DR advantage of the D750 is only 1/2 ev, and that's only at base to around 400 after which they are pretty much identical so are you going to notice this in the real world? Doubt it. Likewise with noise, the D500 is only about 1/2 to 2/3 stop behind (maybe about 1 stop at 12800
and above) which isn't really that noticeable. Add to that the D750 tends to underexpose so if you've not addressed this in your exposure and compensating in post then it makes the images noisier which may be why Rookies is finding the D500 better if he's getting exposure better SOOC with the D500. I find the D750 noise less rough/grainy though.
Either way, he's happy with it and that's all that matters
