I've had an Eotech for a long time and a Vortex Spitfire that I just bought. I like them both. I have about 3,000 rounds through the Eotech and about 80 rounds through the Vortex. I have to wear my glasses to use them due to my eye sight.
Eotech:
- Awesome optic no matter the info out there now
- Great field of view
- Short and light
- Very good run time on the battery
- Easy to pick up your target
- Battle proven
Vortex:
- I like the etched reticle in case the battery dies
- 3x which I like too
- My eye works better with the green illumination than the red
- It's heavier than the Eotech
- Made in China, I hope it holds up
Both have limitations, but as long as you know what they are and what you can do with them it doesn't matter. Prism optics have a purpose, so as long as they will do what you want you will be fine.
The Vortex is on my truck gun, and the Eotech is on a rifle beside my bed.
