I have had BOTH Eibach and Bilstein shocks and much preferred the eibach over the bilsteins. Granted they were both on a tacoma, and then again on a 4runner i ran a 3" eibach pro kit.
The bilsteins were OK, slightly better than stock... But the EIbachs were night and day better, a smoother ride that absorbed more bumps and stuff offroad. And completely eliminated body roll and nose diving on hard braking incidences.
I live 2 miles down a very poorly maintained dirt and limerock road with tons of potholes, washboard sections, and when it rains it floods... The eibachs made a HUGE difference... Not as much as some kits with extended reservoirs, or King long travel... But way cheaper and a great improvement over stock.
You would likely be happy with either of these over stock, but if given the choice and the price was similar i would recommend eibach for sure.
