To me, it's really not about choice of equipment as much as it is an attitude: If you live in a fast-paced world and want success(however you measure it) right away, longbows aren't for you.
But.....
If you hunt to be hunting, love to be in nature, aren't in a hurry, and want to REALLY LEARN TO HUNT, then by all means, try longbows.
You will have a lot of "close calls" before you make a kill......who'd want it any other way?
I can afford to eat anything I want, I don't wrap my manhood around antlers, and if I never make another kill, I've made my share. It's just an entirely different experience with the ancestral weapon.
Good luck.
