Tein S-Tech v. Tanabe Sustec v. B+G Springs

[DSMX921]

I've decided to go with regular springs as I don't adjust ride height often, and i'm just looking for a mild drop to close the gap for 17's. I've come across a few kits that appear to be of good quality. I like the Tein S-Tech springs, the Tanabe Sustec GF210 springs, and the B+G springs. Which ones are the best quality overall?

have you considered h & r sports?

I've considered them, but I like how Tein comes with a gurantee not to sag more than 5mm....just looking for personal experiences with them, and the tanabe and B+G's as well
