Neuspeed and H&R use Eibach springs right? If so, get either of these or Eibach springs before Tein S-Tech. I guess there isnt much wrong with the Tein springs, but i bet they will cost lots more than Neuspeed, H&R or Eibach. Eibach springs are better anyway.
I don't know about their Honda products, but on Subarus, their S-Tech springs are known to have a decent drop, stock ride, but spring rates that are too soft for competitive usage. Their coilovers are known to have incredibly high spring rates, which makes them useless on anything but the track... plus they rust if exposed to salt.
