Rob pretty well nails it. We are blessed with numerous styles of bows. They shoot differently.
Overall, generally, as a rule (have I qualified this enough?) I find that recurves shoot smoother than other bows. They're very pleasant to shoot. However, I find them large, heavy and awkward compared to other bows, but I don't complain about this every time I shoot one. I have a couple of beauties... a vintage Widow and a vintage Bear. I enjoy shooting them and won't part with them, but I don't shoot them as much because they aren't my favorites.
I find RD's are (again insert all of the qualifiers above) better performers. I think the best technical work going into bow development today (speaking of what I consider true traditional bows, i.e. not IFL, metal riser, etc) is going on in RD's. They're getting some incredible speed and accuracy. Also some extremely lovely bows. I have a couple of great ones, a Widow and a Berry and won't part with them. I enjoy shooting them but I don't shoot them a lot because they aren't my favorites.
I have a lot of Hill styles and not just ones I built, Craig Ekin, Ted Kramer, John Schulz and Howard himself. I find them (please insert the qualifiers again) light and wonderful to handle, not as fast, a little tougher to master in terms of accuracy. I love them for their lightness and ease of handling, their extra challenge, and above all because they are, to me, the tradition that I value. I don't find them obnoxiously shocky, but there is more "feel". For crying out loud, they weigh (qualifiers again) half or less what other bows weigh. There are, within Hills, different classes... standard riser, forward riser, reflexed, straight and string follow. Each has its own feel.
All of these types of bows are different. I know I'm a lone voice here, but I think it's really unfortunate that RD's got identified as longbows. To me, they're not the same thing at all. They're RD's and they're wonderful bows, and they should be recognized for their own qualities and merits. They combine some of the best of recurves and true longbows and should be valued as the development they are.
Given the variety of bows we have, it doesn't make sense to me to try a new style because it's different and then complain that it's different. If you try something new and don't like it, or don't master it, go back to what you like but don't put it down because you didn't like it.
Hill styles are the closest we have to the original fiberglass laminated longbows of the 50's and 60's and have, rightly I think, a special place with shooters who value that tradition. So do give them a try, but please, be fair, do it on their own terms.
OK, the grumpy old man is done....
