There's not much difference between a straight Hill style bow and a mild r/'d bow. Both string up into a D shape, both typically have rather straight grips, most times their arrow shelves will be cut proud of center, and there won't be much difference in performance between them. Now, if you go to a radical r/d, like an ACS, for example, there's a huge difference. Pistol grip if you want it, cut 3/16 past center, and performance that equals or passes many recurves. I have all three designs and like shooting all of them. As others have suggested, try a few bows in the designs in which you are interested to determine which you like best. Good luck.
