The title reads Fox vs SN95 so I figured he wanted opinions from both sides.
Meh... plastic is lighter look at new oem..
Looking from a pure performance standpoint both platforms have good qualities. The fox is light most of us are going to upgrade suspension parts from stock so things like U/L control arms, coil overs, shocks and the like are a given on both cars. The fox desperately needs subframe connectors, the sn95 got a lot more bracing than the fox.
The fox platform came with 4 lug wheels and smallish front rotors, to remedy this most do a 5lug upgrade to the car. Both platforms will need upgraded brakes but the fox will need spindles rear axles and a brake booster. The upgrade isn't difficult for most wrench turners. Other options include a rotor and pad swap for the fox which do work well and haul my convertible down from 100mph on an 1/8th mile dragstrip easily enough to take the first turn off.
The sn95 does have a lot more driver assist features, these are important if you can't/don't know how to drive. Or get caught in the rain on a terrible road.
