I always tell prospective pig-keepers to try as many breeds (as long as they are suitable for requirements) as they can when they are just starting out.
Try two of one breed, then two of another, etc. You learn a lot about your own likes and dislikes (both whilst rearing and when you get the meat back from the abattoir).
Nice thing about rearing for pork is that it's not a long-term committment (max four months), so you CAN change your mind next time round. Experiment and enjoy.
