a reflex reticle is super useful on the field at 100+ ft...in cqb... you can just aim down the barrel.
I find the eotechs generally to be really crappy... they aren't bright enough in bright sunlight. If you are going to buy an eotech replica, make sure you try it out first in bright light before buying. Sucks when you spend 50-70 over the web on an optic and it's garbage.
Zoom/magnification is pretty useless for most airsoft guns, your average effective range is about 60-110 feet... When you can accurately hit a dinner plate beyond 150 feet, that's when you might consider getting something that can zoom since that's about the distance you start to lose sight of it without help.
