The Canon is probably a better investment in terms of holding a better resale vs. the Sigma
FTR, this has not been my experience. Having had over 500 Canon and Sigma (and other lens makers) lenses go through my hands (new and used), my experience is it depends on the (1) condition of the lens at the time of sale, (2) how you market and sell the lens (e.g., great description, pictures, forthrightness, etc.), and (3) timing (e.g., all you need is that one person who wants that lens and wants it bad, newbie or seasoned photog).
I've made money on most of my sales, Canon or Sigma. But recently I've snagged some good Canon glass at massively low prices; that is, I wouldn't consider what I paid for them to be "better investments" for the people I bought them from. It really depends on some important factors. I don't buy for one bit the "Canon has better resale" mantra (even though most my lenses are Canon).
