The best possible answer is a D5 (or D4), but the OP will have to balance the (large) investment against future profits and how badly he wants to shoot sports professionally (one of the more expensive genres in terms of equipment costs). Lacking that, I still believe the D750 is the best of the two choices if indoor sports are involved.

I agree that the D750 is better than the D500 for noise in a basketball game because I just did the comparison last night. I used a Nikon 85mm f/1.4 lens on both cameras and the D750 was definitely less noise (I enlarged the subjects from the D750 to be equivalent size to those from the D500, to match the increase in magnification). But I still got noise in the D750. I kept my shutter at 1/1,000 s (aperture of course at f/1.4) with ISO to around 3200. I made every attempt to ETTR. What was the lens used in this study that you referenced above? I am assuming that the ISO values you quoted are the maximum values before the noise became obvious? Based on what you said above, my level of lighting must have been a whole lot less than the study value was for me to get noise at ISO 3200. Thanks for your help. An earlier poster mentioned a 50-100 f/1.8 lens, but I hate to lose the light even though it's only ⅔ of a stop.

giving an honest reply, based on their own experience. I just ran this test last night and the D750 was much less noiser.
