The Vitesse is aluminum, the other two are steel. You can find many long and boring discussions comparing frame materials; I'll generally go for steel. If you examine the frames of the Mariner and Speed, you can see the difference in design, although the Mariner frame is identical to the Boardwalk.
Between the Speed and Mariner frames, I'm not really sure what differences you'd find in performance or durability. To me, the Speed *looks* a bit sturdier, but I have no proof for that. Riding position should be close, perhaps identical. If the Speed D7 has the same derailleur hanger as the Speed P8, then it might be easier to upgrade or replace the Dahon Neos derailleur, if you want to do that at any point.
