I have not decided. I was originally 100% on an eotech but read that they have horrible heat resistance.Not sure if you ever decided. It really comes down to personal preference and night vision use.
Aimpoint: leave it on 24/7 and replace battery once a year. Simple red dot.
Eotech: great reticule for shooting fast, the undisputed king of passive night vision performance. Be prepared to change batteries more often, not something you can/want to leave on 24/7.
