X-H2 vs X-H2s for sports photography

I don't shoot sports photo but I rarely shoot sports photography for my teacher and his students when I visit Asia just for fun. Last year, I used Sony A7IV with 150-600mm but since I switches to GFX system, I no longer have it. Luckily, there are so many rental houses so renting a lens+camera is not a big issue. The reason why I would rent Fujifilm X-H2 or X-H2s rather than Sony or Canon is because I already have Fujifilm batteries, a lot cheaper than Sony and Canon combinations, and not really gonna spend too much money on rental. Beside, since Fujifilm is not that popular, it's easy to rent as well.

​

The questions is which one to rent? Personally, I would prefer X-H2 because it has more megapixels which I care a lot but it seems X-H2s has a stacked sensor and has better AF performance. I shot outdoor baseball games and Sony A7IV was kinda fine except for 10 FPS. But again, this is not my major work so it will be for fun. The rental price for X-H2 and X-H2s is really cheap but I gotta pick one.

Any suggestions?
