Tanabe & Tein are both JDM
They'll both perform the same, so it's really up to which one you prefer. I went with Tanabe 'cuz I didn't like the nasty green color on the Tein (most of you would say that you cant see the coilovers, but I can see mine when I'm walking up to my car
) and everyone else has Tein.
You can't go wrong with either one, so you can flip a coin & decide like that
