I don't think this function is linear.

I think it trends lower on the low end of the "technical ability" axis because it's perfectly fine for grandma who just uses the internet, plays solitaire and occasionally emails, and who needs a family member to sysadmin their computer whether it's Windows or Linux. You can usually drop Mint on their old computer to keep it running and even speed it up a bit after Windows stops supporting it, and save them from buying a PC for awhile.

There's a bump up for folks who are making the switch on their own because they're not used to the ecosystem and might have hardware they like that is poorly supported in Linux; I remember my own early days trying to make the machine I already had work and having to install stuff from Git, now that I choose hardware for Linux compatibility that decreases.

There's a valley in the middle where "This is fine, it works satisfactorily."

Then at the high end of technical ability you have people who have opinions about systemd.
