Knock yourself out but not for me. I’m not a hipster and there are no practical advantages to 9x23 other than being rimless, which doesn’t matter in single stack mags.
The only reason I’d even bother with 38 Super is it’s the correct length to function properly in 1911s. It’s reasonably common, and at least some smaller ammo companies like Wilson load defensive ammo with modern Bullet designs. Power level is similar to +P 9mm which is fine.
