When i had my s2000, i purchased at set of BC br racing coilover's, they where very good for the price you pay, and adjusting them was very easy, for day to day driving on the softest setting they werent that much harder than the oem suspension.
Having said this, i believe the nsx doesnt deserve the best bfyb, rather just the best, a lot of guys that tracked there s2's whent for a higher end tein set up (their low end is pretty ordinary) or, KW v3, do some research into them and i doubt you will find many people who did not like them, but if i was to get another coilover set up, the v3's would probably be it.
