Please note that this list considers 2009 anime only, so don't be surprised if some of the most well-respected studios ever don't rank so high.
The top 2 were easy choices. The rest of the list, not so much. This video is longer than the 2010 and 2011 because, surprisingly, there seemed to be more anime in 2009. Also, I want to stress that positions 25-15 are all interchangeable to some extent. It was hard to get a clear order together. Gainax is that low because the Gurren Lagann movies are summary movies that have a lot less attention than the TV series. I took the high rating with a pinch of salt.
Intro song: "Again" by Yui, FMAB OP1. Had to include all 3 FMAB OPs in the video btw ;)
