If you can, shoot the bows. What works for you might be different for others. The best bow, is the best bow for you. Meaning, the bow that fits you best and feels best, is the best bow. Once you get it, have someone tune it for you. Its also good to lear how to tune yourself. Then read along here and use the search to find info on shooting form, tuning broadheads, releases/finger use, etc. etc. . Then practice, practice, practice. And be prepared to be very patient.
By the way, welcome.
