"Could the most important thing about a camera really have nothing to do with its performance or output? Could how the camera makes you feel really be more important than the pictures it takes?

This makes sense for everyone but the artist. Comfort is where art goes to die.
If you're using your camera as a form of therapy, then use whatever you feel like, but realize that pushing your creative limits and relaxing your brain are two opposite things.
