I guess it depends on what you intend to use it for...distance wise..and possibly your skill level. I am a self professed newb so I am learning to shoot up to 200yrds currently and opted to go with the Eotech EXPS2-0 w/G33 3x Magnifier. Works great for what I am doing, only downside if you could call it one is they do add some weight.
I'm no pro but I've been running a vortex strike fire and vortex vmx-3t magnifier on 14.5 for a couple years and except for a little extra weight it works good.
