Ride height:
H-Tech > NF210
My experience has H-techs 0.4" lower front and 0.3" lower rear than my old NF210s were

Ride quality:
NF210 > H-Tech
H-Techs are smooth, but NFs are smoother

Body roll:
H-Tech > NF210
H-Techs are lower and a litle stiffer. The difference in handling is pretty apparent. The H-techs feel much sportier than the NFs

I think the H-techs are right in the middle of the pack as far as drop, stiffness, etc amongst all the springs available for the xB2. I will scrape with the H-techs now on steep driveways. This was almost never a problem with the NFs. I just took a trip up to OC with 4 people and did not scrape once. The ride was good and handling was very nice. Big dips on the freeway with 4 people feel solid, yet a little stiff.
