i have the tein s tech and love the ride. i also like how it didnt drop my car to the point where it was hard to drive over speed bumps. its just enough. i have heard that the h techs have a much nicer ride quality. But it also depends if you are going to autocross or anything like that, if thats the case then fully adjustable coilovers are the way to go in my opinion or the sti suspension i heard was very nice for autocrossing.
