It definitely comes down to personal choice. The Eotech 553 uses CRV123A's as does the Comp M4, and has a hard aluminium protective shell, nightvision settings, 7mm riser + a cantilever quick detach.
Aimpoint Comp M4 VS Eotech 553 would be a fair test. Me personally, I sold my Comp M4 and bought a 553.
