iCloud with a txt file in/on my Desktop and/or Notes.app. Everything is seamlessly, effortlessly, nearly instantly synced. You can even share notes using Notes.app easily. It's simple enough and easy enough to access that it's the only way I can stick with this setup unlike every other setup and app I have tried. My only negative is that it is yet another variable that has me entrenched in the Apple ecosystem. So, despite not exactly the most impressed with the current MacBook Pro (2017) I own the time and convenience it provides I feel has made up for it.
