I enjoyed both the anime and the live action versions. IINM, the anime is truer to the manga and fleshes out some of the minor plot points e.g. on why Stressemann dislikes Viera Also, great voice acting from Kawasumi Ayako, with her "gyabo" "iyaan" etc

The live action is good too. Great pacing and plot progression. The biggest plus points of the live action: Ueno Juri and the music scenes Watching her play really makes you feel the joy of music, esp the scenes of Nodame and Chiaki playing together. Understandably these scenes would be difficult to reproduce regularly in the anime because of budget constraints
