Everyone has different needs and wants. I like to use the O2 Monitoring especially during the night as I suffer from apnea and use a CPAP machine. Still I love the way it’s less distracting and I deactivated notifications so for all intents and purposes it’s a normal wrist watch that doesn’t grab attention.

I don't need any Bluetooth functions. I've had the same G-Shock for the last 10 years. I never take it off, never replace the battery, works fine.
