I found this to be a good, basic, and very understandable read on prism scopes that explores both its positives and negatives -
Before you buy yourself a prism or a red dot sight you should know which one will be best suited to your needs. That's why we've compared the two in this extensive...
Unfortunately as you noted, prismatics do tend to be a bit more costly than non-holographic RDS offerings, but this is really just par-for-course, due to the optical complexities and components involved.
And similar to powered "traditional" optical scopes, the shooter will not be able to properly cowitness BUIS through prismatic scopes.
^ Yup, unfortunately, it's you.
Alas, not all of us can have perfect vision.
If you really, really want a non-magnified dot and astigmatism or other vision shortfalls makes a traditional RDS limiting for you, the prismatic might really be your thing.
