ive uesed meprolight (pretty bright if you ask me) my PD buddies all use trijicon cause thats what the department went with, cant go wrong with either brand IMO. I also felt that the mepro's were brighter, not by an OMG lot just enough to notice. also might want to look into ones with trivium and a fiber optic. those are really bright all the time. i thinnk truglo makes a set.
