I have a set of the factory Trijicons on an XD-9SC, and they have performed well. But, be advised, the factory night sights are manufactured by Springfield Armory, utilizing Trijicon tritium vials - they are not the Trijicon brand sights.
The Trijicon brand sights have white outer ring surrounding the tritium vials, presenting a slightly larger dot in the daytime.
The factory night sights, from what I have read from numerous sources, seem to have a higher rate of dissatisfaction from problems like dislocating vials and vials going prematurely dark.
On my XD-40 service I recently had Truglow TFOs installed, and I am very pleased with them as well.
