You claim to be a "poweruser", but then go and speak out of pure ignorance when it comes to Linux.
You say "Apple hardware is beyond superior", when in reality Apple glorifies form over function with soldered, unserviceable parts (and actively lobbies against self-repair), and removal of ports (very anti-poweruser, if you ask me), all of which turn their laptops into disposable gadgets meant for the consumer demographic first and foremost. I'll say Apple displays are great, though.
Your comment about "just works" betrays your preference for abstraction (once again, not a very "poweruser" sentiment), and shows ignorance (Wi-fi: macOS maintains a whitelist of wifi adapters, to the annoyance of "hackintosh" builders, and has far less wifi support than any Linux distribution. Backups: Why would you ever want to abstract this to some software interface? There's too many tools to name which you can levy for your needs on Linux, e.g. rsync, tar. Sharing: SSH).
"Poweruser"? No, I feel the more accurate term would be power-consumer.
