So I have a Aimpoint Comp M4, I like it and I know it's a little on the large side. So far I have it paired with an Aimpoint 3X magnifier, the older "pro" model. Both work just fine but I now realize I have more powerful options:

Sig Juliet 4X and 6X
EO Tech G45 5X

So I'm thinking that a 4X option just isn't enough of a difference from my 3X to justify the money. A 6X seems like a good option but I haven't heard anything on it. I really like the idea of a 5X too and I've heard good things about EOTech glass quality. So which would you choose or presently have? What do like/dislike about them?

Thank you
