Haven't tried the Phillips, but have tried all 4 versions of Nightbreakers from the original NB, through NB+, NB Ultimate and NB Laser. Currently have NB Ult in dips and NB Laser in mains on the S204, marked improvement over standard bulbs, not convinced yet that the NB Lasers are better than the NB+ that were in the mains. Happy with the NB Ults in the dips (which are on full time as my S204 does not have DRL's).
