It's all pretty subjective Dave. If you're pounding the pavement around town and some medium distance rides, a Softail or one of the Dyna Lowriders are pretty comfortable. If you're planning on any real distance rides, I would recommend something with a full swingarm suspension like the Road King, Electra, Road Glides, etc.
I have a Softail Custom and have ridden all throughout NE. All trips were day rides or an overnighter. Something that you can pack light for.
It's all about what fits your style of riding along with what you consider eye candy in the styling aspects. I always liked the stripped down bare bones style, but as I get older, I've considered getting into something a bit more comfortable.
Here's my scooter.
