Leather if you like your guns finish
I'm going to try a hybrid. I have a light weight leather IWB that I don't like. If I holster after putting my pants on, the slide on my shield will open. So, I always holster the gun before getting dressed. My Alien IWB is on its way. The kydex will stay open when inserting the gun, plus I do like the click as the gun seats in position.
