I've got a non-cup chassis 200. I do a fair amount of motorway miles, having driven a few cups I'm more than happy with my set-up. I think Evo summed it up best. Both great to drive, the cup chassis is better when you drive really hard. Up to you wether having a firm ride (and it is very firm!) 100% of the time is worth it for maybe the 5-10% when you'll feel the benefit.
Optimum setup for me would be the cup rack, with the non-cup chassis.
