RE: choose pendent or upright sprinklers?
In Asia and the middle east, it seems they use pendant where ever there is a choice. I suspect the upright suits freezing climates so that when you drain the system, there is no traped water. Pendant sprinklers are a little easier to install from below. Also what installers tend to do in underground carparks in Asia is get rid of the treaded rod and the nut that comes with hanger and bolt the hanger directly to the slab. This gets an extra inch or so of head room in the installation.

Another point is that with pendents there is more possibility of trapped debris on the sprinkler, when there is and evidence of dirty pipes on a internal pipe inspection.
I´ve seen a case in a sport goods store where they used the pendent sprinkler deflectors to hang backpacks.

if you will compare them, they where actually the same performance provided that you are comparing them with the same characteristic. e.g. k-factor
installing upright or pendent sprinklers will depend on the situation and application you are using them.
for example: you will use it to protect a room with ceiling, you will choose upright? of course not, you will use pendent to protect it and your piping will be on the ceiling space.
