Which distortion is better?

1

2

Probably 2. While 1 has slightly less bass roll-off at 16 Hz, it will be more affected by load impedance variations due to the output coupling capacitor.

Your distortion simulations look like settling is incomplete.

Thanks 👍

Is it ok? 🤔

The loop gain plots look good to me. The distortion simulation results look good, but I can't see whether settling is OK without a spectrum plot.
