It's not really a 100% fair comparison since the Fox 2.0s are a true front coilover kit, while the Bilsteins are a strut replacement that reuses the stock spring, perches, and mounts. That being said, their on-road ride quality and handling is pretty similar to each other in being slightly more stiff than stock, but they also greatly improve overall handling, reduce body roll, and the rear shocks take the bouciness out of the rear end. Off-road, the Fox 2.0s offer superior performance than the Bilsteins, and can take harder impacts with more composure while suffering less fade at speed. Still, the Bilsteins are less expensive than the Fox 2.0s, and will do fine in most applications.
