What is your favorite red dot?

Like lots of other people I'm getting a lot of my ducks in a row now that I have a house. Was thinking about getting a shotgun, probably a mossberg, 590a1, and putting a red dot on it. What do you recommend<br><br><br>EDIT: Thanks for all the responses everyone! Think I'm gonna go with the aimpoint micro, the heritage roughrider, and trijicon night sights.
