i have experience with both (mostly mechanical, not riding) i have a friend who currently rides an orange 222, and another friend who used to have a vp-free.
both very nice rigs, the vp-free is the smoother ride and tends to hold its line a little easier, the orange is generally a more solid ride, slightly better over stutter bumps and the lark, but is a little easier to push off line through the rough stuff.
as for strength, the orange is a single pivot, with a massivly strong swingarm. theirs alot more to go wrong the on the cruz. but at the end of the day the only way your going to break either of them is through poor riding.
