I similarly use cantilevered rail extenders for my scopes that have trouble mounting close-enough to my eye.
I think I only had to do it for two of my scopes, the "no eye relief" prismatic scope and the Sightmark Wraith Mini. Everything else I have either has a built-in cantilevered mount (like my thermal) or they're fine being mounted further up. For the Wraith Mini it was kind of borderline -- I don't really need the rail extender, but it makes it far more comfortable for my neck.
My preference is the ADM rail extenders as they're quick-release. So if your scope doesn't have a quick-release on it, at least the rail extender gives you that option. They also pretty reliably find zero on re-mounts. I haven't tried every variety of rail extenders, but ADM is high quality and gives you quick release, as well as making mounts compatible with a wide variety of scope bases.
