Head size is the biggest reason. M8's have a 12mm head (instead of 13) and M10's have a 14mm head (instead of 15).
I don't know if you can get stainless at AAA metric for the JIS hardware. Last time I checked their inventory was all zinc-plated. But Ace and Jax have a small supply of standard metric stainless IIRC.
