AF performance on M bodies compared to M3?

I recently upgraded from an EOS M3 to the R5, mainly because of the EVF and because the M3 AF was just too frustrating, super slow and then just focusing on the background even with the center point. I got some great pictures but also missed lots of shots.

The R5 is awesome, but now I have a bunch of very used EF-M lenses with little resale value sitting around, and I'm thinking of getting a used M body. Doesn't have to have EVF, but faster AF than M3 is a must.

The M6 II is still rather expensive used, so I'm wondering where the sweet spot for older bodies is. How do the AF systems on the other M bodies compare to the M3?

The M6II has the best AF of all M bodies, by a large margin, it's the only M body that can do eye-AF in servo mode. Having said that, it's not R5 level, it's somewhere between the RP and R.

The AF on the M50 is a huge step down from the M6II, but you can use some workarounds, like selectively enabling continuous AF (which is different from servo-AF!) and bribing your kids to sit still.

This is why I keep hoping for an M300 that has eye-AF in servo mode :)
