I've got a shoulder and an IWB holster. Depends on what I'm wearing, and where I'm going, and how sort my back may or may not be among other things. If you're asking to find out where YOU want to carry, don't pick just one- especially not just the "belt" which is more than one for most of us. You'll want a belt and a non-belt method.
Ankles and pockets are usually for backups or around the house carry.
