Depends on type of notes - shopping list google keep(in case they shut it down there's omni notes). Otherwise I use markdown + latex(math) in whatever editor I have at my disposal. Then I view it in e.g. hackmd.io / VSC / neutriNote. I've tried word, onenote but it didn't work for me - writing formulas and equations is much faster in latex. I don't go full latex though because markdown is much more readable in its raw form. Graphs are still pain though, haven't really solved that, especially those without absolute values.
