I do both pretty hardcore right now and there is ABSOLUTELY a difference between a compound and a traditional bow and what it takes to hunt successfully with one, no doubt about it. But also make no mistake compounds are still archery.
I see it every weekend at the league 3D shoots. There are some elite compound shooters who make it look EASY. Some who are good and then others who are darn happy making consistent kill shots at ranges where I am pounding x after x.

With a compound you still have to actually learn how to shoot, and probably the biggest thing that separates compounds from crossbows.............draw the bow at the moment of truth.
You still have to draw it back (regardless of let-off) and hold it up.
True you can hold it back longer but once that bow arm goes you have to let down and that depends on how strong the shooter is.
NEVER confuse it with a "bow" that is cocked and ready to go and can be rested on a shooting rail waiting for the right angle.

Bowhunting is pretty darn tough for even a majority of compound shooters, the traditional guys just seem to enjoy a little more of the "romance' of the sport and can be darn proficient in the process.

I do both, I LOVE both and feel no pull toward the elitest side at all.
