Yeah, it's a valid comparison. I will let you in on a secret: I have a full 1990s' Britannica set in my home, about three metres from my desk.
I consult it maybe four or five times a year, and the Britannica website maybe another dozen times or so.
Still, it's good to always be aware that the ways Wikipedia and Britannica are produced are very different and to factor that in (see my post below from just a couple of minutes ago, about the desert article).
You know in the world of tech they have a similar saying: "No one ever got fired for buying IBM."
This does not mean IBM is either a superior choice, or a wise choice.
