FIST hybrids...Leather exterior bonded to a kydex interior. ANY of their holsters can be made as a hybrid.
As for which is best over the long haul...IMHO, flip a coin. Plastic cracks and when that happens it's trash. Leather requires a bit more care but a well made well cared for leather holster can last a heck of a long time.
