Well, it's all talk to be honest; I can't see myself ever buying a Harley, and I'd certainly want to try them out beforehand. Still, I'm sure I'd be happier on either of those (and live longer) than on a Hayabusa or something...
If I'm completely honest with myself, with the financial difficulties I went through, and basically "starting over" at fifty, I have to admit to having doubts that I'll ever have a bike again. Maybe I could swing it by the time I'm 55, but do I really want to get back on a bike at 55? I suppose it would be doable living in a small town surrounded by farmland like I am now, but still, I have to wonder. I miss it, but then I miss a lot of things. Other interests come along, and maybe that's just the way it goes...
Edited to add...
You know what's really perverse? I think I miss working on a motorcycle just as much as I miss riding one. I had more fun with my down-80%-of-the-time '82 Yamaha than I had with my reliable '06 Kawasaki. Maybe I should just find myself a junker that still has decent compression and dive in.
