Sony a9 vs sony a9 ii?

Both are 24.2-megapixel full frame mirrorless cameras with in-body stabilisation and the Sony E mount, so the sensor and lens options are essentially the same. The Sony a9 came out in 2017. It's a stacked-sensor sports camera, and I'd call it a used bargain if fast action is your main subject. The Sony a9 II followed in 2019. Beyond the announcement dates, I don't have a detailed side-by-side to offer, so price and condition will likely decide it.

Whichever you pick, these lenses suit it well:

If you want a global shutter for sport, look at the Sony a9 III instead.
