Was able to shoot some other red dots recently. One thing I noticed is that some dots are crisper than others, at least with my vision. I do have astigmatism, which is corrected with contacts. With rifle, I do notice that the Aimpoint 2 MOA dots tend to bloom, especially on higher settings. However, the EoTech reticle seems to be much clearer. I also noticed that the EoTech reticle is much sharper when viewing with my left eye, so maybe something to do with level of correction.
Anyways, I think it was the Leupold Deltapoint, but I recall the dot being a pretty crisp circle. It was a larger MOA dot. I want to say 7 MOA or larger. It was an older dot and not sure on the model. The current models appear to be a 2.5 MOA dot or a 7 MOA triangle. Anyways, side-by-side with my Trijicon RMR 3.25 MOA, the bloom of the RMR was noticable. I could actually get the RMR brighter in the sunlight, but the Deltapoint was certainly bright enough.
I also tried a gun with the Sig Romeo, but not sure which model.
Anyways, will see how the ZEV slide with Trijicon RMR does this weekend. Have been doing more dry fire and I am picking up the dot better, but again, will have to see how I do in live fire. That said, I am interested in trying out other brand dot options.
