What are your riding goals?
I ride Western, because that's how I started, and I'm fascinated by the ranch horse. I'm planning on doing an internship riding colts at a ranch soon, where I'll gain more training experience and learn how to work with cows. The riding I do now is mostly trail work, which can be done either English or Western. But I'm western through and through.
If your interests lie in dressage or jumping, try out an English saddle. If you want to learn to rope, try a Western one. Better yet, take lessons in both, and see what you prefer. You might want to do both. Experience everything you can. There are so many disciplines, not because some are better or worse, but because everyone has their preferences.
