Different holster makers have different holsters and depending on the gun or how I want to carry it may dictate the maker. Lou Alessi makes a great ankle holster, xdraw, belt slide, and pocket holster. Tony Kanaly (Milt Sparks) makes one of my favorite pancakes. Ken Campbell makes a super IWB. Kramer and a couple of others make my favorite type of Vertical Scabbard. As far as who I don't like, as a person Gene Desantis, he also is mass producer so shouldn't really be included. Jim Murnak an I had a run in a few years ago and although he might make a good product, I was not impressed with his product nor demeanor. Last would be Mitch Rosen. Pretty full of himself and don't ever have an H&K P7 holster made by him. Again, these are all personal so you might have had different experiences.
