Check out FM's new DS 2-0 which includes some interesting changes regarding ESFR's based on recent testing. As I recall, the downward momentum of the water out of pendent ESFR's was demonstrated to be superior in getting through the fire plume, hence listings for ESFR pendents going forward differ from those of uprights. Please correct me if I'm wrong.

I know you get a couple extra inches of space allowed from deck to deflector but other than that is one way better than the other?
