Another thing that people always say is that "tint doesn't matter", particularly in reference to the RMRs, with argument that you're being target focused, so you're just superimposing the dot over the target image, so the view through the RDS doesn't matter. I would argue that is absolutely false, that the tint can have an impact on your shooting performance for many people. Now, IME, it only manifests itself in certain conditions, mainly in low-light against small targets, particularly if there is low contrast between the target and the background and/or your lenses are all scratched up; the problem is that the superimposing of the image confuses the brain due to the discrepancy between the images; in something like an OEG, the dot is against a plain black slate, so it's easy to disentangle the plain black against the target, but when it's two similar images not quite lining up, it can definitely slow you down, as you try to reconcile exactly what your dot is aiming at. Is this a major issue, enough for me to not recommend the RMR? Not at all (I would still be on the RMR if I weren't on the ACROs), but it is a nuance to be aware of in a defensive application.
