I don't meant to sound flippant, but "better" for what? What would better mean for you? Are you looking for income from dividends or share price growth?
You're comparing a commodity broad basket fund with leverage to a real estate investment trust (REIT) with leverage. It isn't so much for me a question of which is better, but which sector do I think is going to perform best over whatever time period I have in mind for the investment. Commodities or real estate related stocks?
