I have a troy and it's sick. I haven't ridden the others, so I can't objectively say it's the best of the bunch. What I will say is it's firm under pedaling and plush on descents. I think all of those bikes will be that way for you. I think it would be a matter of figuring out what angles and sizes fit you best, along with aesthetics and spec value. Obviously, riding them is the way to go, but at least with regards to Devinci dealers; they are not plentiful in the states.
If you go the troy route, you might want to look into the XP spec and upgrade from there. The only reason I mention that is, you get the Pike with the XP kit. You can get it with the carbon frame for a $500 up charge from what the XP alloy build is($3500 total). Depending on what the prices end up being, it might make more financial sense to get that build and swap parts.
Good luck with your choice. You won't make a bad decision. It's nice to know that regardless what you pick, you'll get a sick looking, sick riding bike that will likely do pretty much anything you want. Take care.
