I'm gonna answer you in two parts...part one will be my summer AIWB rig since the majority of the thread has centered around AIWB and part two will be my winter OWB rig.
AIWB... I use this one:
https://tuckergunleather.com/cover-up-plus-holster/
It's a bit expensive and I probably would never have bought it for myself. But, it was a gift to me, so I used it. And liked it.
Smooth outside is easy on the skin, the belt clip is adjustable for both height and cant, adjustable retention, full length sweat shield, the holster itself is about as minimalist as it gets, and the holster mouth is reinforced so it stays open during reholster (even though I personally remove the holster and put it back after reholstering).
Drawbacks are the screw setting cant will work loose periodically. Blue loctite will probably take care of that, but Ive just never done it. Keep an allen in my truck ashtray and one in the nightstand.
The plastic belt clips are another point of failure. I broke one last year taking the holster out of my pants to reholster the gun. Bought a three pack of replacements online for about 7-8 bucks.
Another drawback is the price for what it is. But, it has been THE most comfortable holster I have ever put on AIWB. Of course, ymmv.
This one was built for a P01...then I started jamming Cajun goodies in both P01s and switched to carrying the PCR. I just tightened down on the retention screws real good and it's worked fine.

Winter OWB rig....like
@SPST it's
@chiefjason leather all day. No substitutes. The Mrs does not like IWB at all, so she carries hers in his leather everyday. At least until he finishes her G26 holster *cough cough* lol. Then she'll carry the 26 *barf*
