Best for What?? Ride or Handling?
I think Eibachs give a better(sfoter) ride, also the drop they give makes the car seem a little lower in the rear than in the front.
Neuspeeds/H&R(same springs) are stiffer but have better handling. They drop the front more than the rear for a more even appearing drop.
What do you want cuz I would stick to one of these 3.
