depends:

for airpod max, the sound is same as the stock fabric.

for Steelseries Arctic Pro, sheepskin leather sounded better than stock fabric.

for SennHeiser HD800s, leather caused a tighter fit because its thicker cushion.....that changed the sound dynamic vs the stock fabric. I went back to fabric because HD800s are known to be loose fitting - less clampy, whcih is why its the best headphone out there. can wear it for 12 hours and not notice it.

For yours, you may already be accustomed to a clampy feel.
