For general ring riding (or even a bit of trails), I would probably go with a training saddle. They're comfortable, put you in a good position, and can be used in low-level showing.
Saddles I would definitely avoid are barrel saddles, cutting saddles and reining saddles (even though I love them). They tend to put you in a very specific position, which is good if you ride barrels/cutting/reining, but isn't preferable for other disciplines.
