Pretty much my exact experiences. Banking and large corporations: RedHat, because they buy support contracts to have guaranteed security and stability updates, and because they want some assurance that whatever (open/closed) corporate software they use will run on their Linux systems. Debian and especially Ubuntu the last years for smaller "dev" companies because the devs like to be close to the open-source ecosystem. I've never met an individual (not corporate server) or end-user (desktop) running RHEL though. Back to topic, I've been following Btrfs... At one point it seemed destined to become the default for most Linux systems, but I'm not sure where it is headed now.
