Each Nikon camera is different with respect to autofocus. I have had the D1x, D100, D200, D300, D2h, D2x, D3, D800e, D810, D850, D7200, D500, D610 cameras and they all performed differently. Group AF provided no benefits with the D750 but it works incredibly well on the D500. Dynamic AF performance with the number of points chosen works differently on each and every camera.
The new 153 point autofocus system with the greatly increased number of cross type autofocus sensors and a dedicated AF processing chip, is a huge leap forward in autofocus performance. The D5, D500, and D850 are a class apart from any other camera from any manufacturer.
With the D850 I am getting good results with DAF 25 points and with Group AF. Group AF works better on the DX D500 camera as there is less chance of having the camera focus on the wrong part of the body or the wrong person in a group as with dance floor action.
Steve Perry put together an excellent e-book on the Nikon autofocus system and it is worthwhile investment.
Back Button AF-C is what I use all the time. It was the switch to back button autofocus that was awkward at first but now find it extremely helpful and enables me to shoot faster. Before the switch I would focus and then use focus lock and adjust the frame and then shoot. Much much faster with AF-C and BB autofocus.
