Red dot are better in dark environement.

I would definitively stay away from fake acog as the acog have very small tube,wich is quite bad for quick target acquisition. I personnaly run a M2 and a micro T1 (both replica) on my cqb (and some time outside) setup.

Also to support what Brian said, Some replica (my Ak is a good exemple) dont have full adjusment. So sometime it's the only way to have at least one reliable sight.
