I don't shoot one, yet.
Tried a Hill bow at Denton Hill, but the handshock was pretty bad. That said, the bow wasn't matched to my draw length or arrows, my grip was probably wrong, etc. In short, I'm not basing judgement on that one limited experience.
I have a Mahaska longbow, that when I do my part, it's almost surreal how it silently just drops an arrow into a tiny spot. It's a bit more sensitive to hand placement than the Super Kodiak.
I'd like to get a true ASL with a straight grip and slight string follow. The will and the $$ just need to align.
But to answer the OP's question, the attraction for me is the simplicity (in looks, it's no more "simple" than my Super Kodiak) the tradition.
