Fair. Both are sufficiently ancient, but cellulose bearing species diverged earlier chitin bearing ones. Exact timing on it tho is nebulous. So either will do.

I only mention cellulose specifically because it is the historic precursor to the first man made plastic, celluloid. But there are now processes to convert chitin to chitosan, which is a moldable plastic.
