I think the question is slightly flawed... There should be a third option that more accurately reflects the "investment" side of things: "Do you buy notes mainly with the objective of selling them for a profit at a later time?"
The two options presented give two positions: a) the fence-sitter who is neither an investor nor a collector (or is both), and b) the collector. You're missing the investor who doesn't really care about the items themselves as much as they do the money they can make from buying and selling.
Personally, I would put myself into the fence-sitter role whereby I try to make smart decisions when purchasing notes, but the notes go into my collection and except in rare circumstances, they stay there. Sure, I've bought notes specifically because I knew I could make a few bucks on them, but that's not my normal activity. I also from time to time ignore the catalogue because I want a note.
