I think you will find the general consensus with everyone that has tried the Bilsteins is that they are quite good. If you read through the groupbuys for all the models, you will find a lot of people have gone from Teins and the like and are extremely happy with them, much more comfortable and better handling.
If I were you, I'd go the Bilsteins. I have them in my 32, but coilover kitted with race coils and revalved. I have never driven on anything like them, and I've had Tanabes, Teins, Cuscos and driven on HSDs once.
