I can't comment on the comparison between NSs, but I can say that, last week, the bride and I took our Glocks down to Smyrna for NSs. $57 per set installed. The Glock guy said to bring the guns back in 8 years for a free NS replacement.

Trij HDs gets my vote. Have the Yellow HDs on my G22 and Orange HDs on my XD-S, talk about fast target acquisition, and accurate too. The TruGlo TFOs on my G23 is a close second cuz the sights seem to glow during the daytime due to the fiber optic, which on the other hand is also its weak point due to fiber optic rods not being as durable. The Trij NS that came with my G19 and factory Glock NS(Mepros) on my other G23 aren't even in the same league as the Trij HDs and TruGlo TFOs, imho...
