It's odd how in my experience SE stamps generally are valued lower than
full-perf stamps, for they are considerably less common. but I understand
that European collectors do put a premium on them. Is this true?

I have seen these, and you are right they are valued lower. The reason is
that it is hard to verify if they are actually the edge of the pane or were
accidentially cut some other way (damaged). At least that is what I surmise
the reason to be.
