The main reason the 2012 Broadway Revival Cast Recording has supplanted the 1996 Film Cast Recording as my favorite version of the Evita score is because I ended up enjoying the cast and the arrangement of the former more than I did the cast and arrangement of the latter (even without Another Suitcase being an Eva song). The fact that the 2012 score features the entirety of the score from both the original production as well as the movie also puts it over the top.
Regarding Elena Roger's performance as Eva on the 2012 recording, I love the way she plays off of Michael Cerveris, who really is the best of the 3 Perons I've heard (even beating out Jonathan Pryce, which is hard to do). I also prefer her performance on the 2012 recording over her performance on the 2006 London recording, even if some people think she's vocally inconsistent on the former. She seems more 'confident', vocally, IMO, on the 2012 recording, and just 'gels' better with her castmates (especially Cerveris).
