None of the scopes you mentioned were 1x, co-witnessing won’t be a thing. Even an LPVO at 1x won’t really cowitness like a red dot would.
I like 1.7 because it’s worked very well for me and many others as a red dot height for a long time. On an LPVO, it’s a great balance between heads-up posture and still being able to easily get behind it in the prone. I have no experience with higher power scopes but the lower 1.54ish traditional mounts always made me feel like I had to smoosh my face into the stock to get into the eye box.
