I want an ACOG. What is absolutely the best ACOG to get for the M4 platform?

I already have several high-end LPVO, Aimpoint, and EOTech.

Some will say the 80's is calling and wants it's optic back. I get it. This is something I want. There's a bunch to choose from. Money no object. .223/5.56. No reticle preference. I think I prefer LED but can't really tell you why.

Dazzle me.
