Pockets range anywhere from abominable to very good. I've been lucky in avoiding the really terrible ones; even a couple of 1970's horns are fairly good players. In recent years, I moved up to a Dillon pocket trumpet and thought I was very satisfied - and it's still a great horn, especially for the price. But when I added a large-bell Carol to the collection, it became clear that an excellent pocket trumpet can play right up there with at least intermediate-level trumpets, if not better. It plays nicely in tune throughout the range, has a full tone, very responsive; a little tight on the hands when trying to work 1st and 3rd slides, but manageable. When I practice with it, none of the people in the house can tell that I'm not playing one of my better horns. For my purposes, I can't justify a Benge or Kanstul pocket trumpet, but would bet that they're even better.
