Having only ever done Rotary, and starting in middle-age, it can take a while to get the hang of the thing (70+ hours rather than the minimum 45), and like most of my fellow-middle-aged students, we had a very healthy respect for the numerous ways helicopters can bite back, bordering on paranoia...
Fixed-wing students of a similar age seemed a lot more relaxed about their training, and seemed to pick up the skills a lot quicker.
Young whippersnappers seem to be irritatingly able to jump in and fly without a care in the world
I was hooked within about 30 seconds of the trial lesson, and being able to land in your back garden just can't be beat. As has been already said, it's the ultimate toy!
Good luck whichever you choose, just get airborne!
