Hi and welcome
Both are good bikes.
An AT is no quicker than an Alp 650, they're bigger and heavier the fuel pump can give issues as can the rectifier and corroding brake calipers. Ironically these these don't seem to be such an issue on the Alp - the Alp doesn't have a fuel pump.
I think it's fair to say most AT owners buy for the more agressive looks - which is fair enough
The AT was discontinued from Honda's lineup some years ago, wether this is an advantage or not is up to you!
For the record I'm on me 3 1/2 Alp - with other bikes in between, never been tempted with an AT for some reason.
You will also get a better/newer Alp for the same money, what is your budget?
As for meetups, I occasionally meetup with Paul (24lb) for a camping weekend/runout in Derbyshire and there is the ocasional meet at Squires near Tadcaster which can draw members from afar, I'm happy to discuss the finer points of Alp ownership if you want more info
