No Country for Old Men, The Dark Knight, and Inglourious Basterds, who would win "Best Supporting Role" if they were released the same year?

I was just wondering, since I like all 3 movies, and all 3 of them won the oscar for best supporting actor in the years 2007, 2008 and 2009.But if they were released the same year, which role would have won the oscar then?I thought it would be nice to hear peoples opinions on which of the 3 is better via /r/movies https://ift.tt/xCE4Vtb
