After auditioning the 2C and the Clear I bought the Clear. I liked both but found the Focal more impressive. That clarity and resolution is exceptional. However after a few weeks with them the intensity of the sound started to bother me. It is not a relaxing headphone, always sounds 'full on' so I got rid of it and bought the 2C. The 2C does not have the clarity and resolution of the Clear but it has a 10/10 bass (while the Clear's bass was 9/10 to me). The 2C sounds big and dynamic while it still maintains some warmth and smoothness. Intense and relaxing at the same time. The Clear was just intense but not relaxing at all. I heard good things about the Auteur too but never tried one. To me the perfect bass is mission critical (deep extension, good sub-bass, clarity) and only planars can offer that. All of these three headphones are great, but dynamic drivers will never have the planar's flat bass extension down to 20Hz. With most music genres this is not really an issue but if you listen to a lot of ambient/electronic/modern music with a lot of deep and layered bass planar is the way to go.
