I prefer the MMS. No zoom but a clear sight picture and the random see dudes through a wall is cool when it works.
The target finder restricts my peripheral a little too much since I am constantly moving but with stock on an LMG it is pretty great. Also, I've seen a decent amount of cold blooded users recently. --- "Cover your receptors Perceptor." Driver picks the music. Shotgun shuts his cakehole.
I find the reticles inferior. There is a lack of periferal (sp?) Vision. It puts you into the mindset of looking for red diamonds instead of looking for the bodies of other players and that is all beside the point that I can just use the iron sights and spend that point on something else
I do like it on a lmg for carrier and sometimes aftermath however --- Want to learn how to procrastinate like me? I'll tell you how tomorrow
