Tx, I have experience with both Hill style and R/D bows, and truthfully, I can't say I shoot either one better than the other. However, I am a diehard Hill bow fan, so now that is mostly what I shoot. I have 5 HHA longbows and 2 Northern Mist bows. All are 68" long, even though my draw length is only 25". Some say that puts me at a mechanical disadvantage, but it just seems to draw a bit smoother than shorter bows. One of my Hill style bows, a NM Shelton is made of yew while all the others are bamboo. Yew feels a bit smoother to draw but the bamboo may be a bit snappier. I have 6 R/D bows but only shoot 4 of them. Three are Archery Traditions Bamboo Longhunters and the other is a Deathwish by Steve Welte. They, too, are 68" long. I like them very much. I consider them equal in performance to the Hill style. Both style bows feel good in my hand, and I don't feel underbowed with either style. So, I guess you could say my Hill preference is mostly based on a whim.
I shoot only wood on my Hill style bows (largely due to tradition). But I like wood, and it seems easier to tune, at least for me. I have used both wood and aluminum on the R/D bows with superb arrow performance. It is just a question of preference.
As you might guess, my opinion is that there is no wrong choice between the two styles. I would suggest that you talk to many archers, read a lot of material, and shoot as many of each style as you can. Then choose whichever strikes your fancy. The bow that feels the best and in which you have the most confidence should be the one you choose. You may, in the long run, choose to own both styles. Nothing wrong there.
Regarding bow draw weight, my opinion is that most any healthy man can probably handle a bow in the 50# to 55# range. Just work up carefully to avoid injury and form issues. My bows are stretched out between 40# and 78#, but as I am now a bit older, my hunting bows are in the 50# to 55# range. I like heavy bows, but it is not at all necessary to go heavy, so don't put too much concern into draw weight All this stuff is merely my opinion. I am certainly not an expert, but I have sent quite a few arrows down range with these style bows, as well as recurves in the old days. Good luck on your quest. Have fun!
