Org-mode for notes, because notes tend to have variable meaningful life sometimes till the entire human life, so I need a stable tool and Emacs is definitively one, not a service who might disappear or change terms suddenly, no matter if I still have my data, missing the tool to use it my way, and well, that's enough for me.
For basic todos like "buy the milk" I've tried for a little time Home Assistant tasks, very basic more comfy than Orgzly, but I do not need much of such lists so... I do not much feel the need of anything special. I've used of course in the past paper notes, I tend to forget them when used as reminder so they are not better for this specific usage, while I still have a small A7 notebook for sudden things to note when I'm not at the desktop.
