Whichever one fits you better and gives you the ride you want. I can't get a good fit with the FXs, but the Cannondale frame fits like a glove. You may need to go larger, but were you fitted to the Cannondale before you rode it?
And a Quick 3 or the Sirrus would be more road oriented. But for a short 4 mile ride, any of them would be fine.
