Personally, I enjoy using both, although I haven't really liked the sabot usage. I prefer a 385 gr. Great Plains bullet or Round ball. I have a .50 Hawken, .50 Kentucky Pistol and a .50 Buckstalker modern. I like the modern design for hunting and put a Tru-Glo aftermarket Ghostring & glowing front globe site on it. Big improvement over the factory sights, which broke after a couple outings in the cold. I don't really care for scopes and have only one on a .22 bolt action rifle that I use to shoot ground squirrels, woodchucks and such. I also have Kwik-Sight Scope Mounts and find that quite often I'll use the iron sights for offhand in lieu of the scope.
I love the look and feel of my Hawken though and can shoot the 10x10 gong at 75 yards with my 10-1/2" barreled pistol. I think it's a case of, "to each his own". I love shooting all kinds of weapons personally, albeit I'm not a real fan of small leads. My center fires are .45-70 gov and .45 Colt
