I ahve the 1dx series but no idea what a 5d4 is...
Here's my take on it- why not try them out on a say a none league or Sunday League game - easy enough to work out what's best by looking at the images

Are you suggesting pictures form a non league or sunday game have less value ?
The pixel count only matters if you expect to sell very big prints and usually that is unlikely.
Good point. Overall, I'd still go with the higher frame rate if I had to choose....or if you intend to crop the image. Which you sort of do in sports photography. Quite a lot.
