Red vs Blue

What say you? Does anyone absolutely love one over the other? Can a Red teamer become a blue teamer or vica versa? Is there beef between the two?

I am a Red teamer (gov clients) and love it, there is a new challenge everyday and I never get bored. There are aspect I enjoy less but couldn't imagine doing anything else. I have never actually me a blue teamer. I have heard blue teamers suffer burnout with overly redundant SOPs and crazy schedules.
