Seems like the obvious tradeoffs you'd expect, mostly lack of control/ability to change things, which I'd expect of MacOS. In return you get stability, Apples locked down approach means the OS is far more predictable. Linux in my view takes the reverse approach, you lose stability relative to MacOS in exchange for complete control. Historically Windows has sat somewhere in the middle, though in recent years with all…
Stability ???? Ubuntu is far more stable. Have never had issues wrt stability. I have had issues with support as in some software do not work on linux (Turbo Tax , Games etc) but never in stability. Have been using linux desktops since 2010
Thats probably why its so stable for you, you know it well, and that increased control of it allows you to make it as stable as you need.
However, generally speaking, Linux does not specialise in stability
