Etching would defeat the purpose of the EOTech and Aimpoint. An etched reticle is stationary in the tube and is affected by parallax.I wish the Aimpoint had the EoTech retical, and was etched, then I'd be almost perfect IMHO.
Aimpoint hands down. Get a 3X magnifier on a Larue mount. You are covered near and far.
The TA31F(4x) has a 1.5" eye relief and the TA11F(3.5X) has 2.4" eye relief. Anyone encounter a problem with the TA31F having too short of an eye relief? The TA11 has a slightly larger objective 35mm vs 32mm, any real difference between the two?
Unless you do that, in which case, Aimpoint/3x is more versatile
