I can't solve complicated problems on a keyboard, I need a pen and paper for deep thinking. It's very rare that I go back and read any of it, means to an end.
That's actually the lack of freedom that killed it for me.
Drawing a diagram, it frustrated me to no end to come at the bottom corner of the page and need to either redraw it all on some bigger canvas, or try patch a sheet to extend it, or continue on another page while looking back at the previous one. Same for the max length of a single line.
In figjam or miro the canvas just expands infinitely, it's near A3 size yet I never run out of paper, never run out of color ink, never run out of post'its etc.
It's slower, but I never have to think about the material side of things, which is incredibly freeing to me.
To each their own of course, at this point I think the options are just a lot more balanced than 5 or 10 years ago.
I used to do it in sequencing programs like PlantUML, but moved to draw.io -> figjam afterwards, with mouse and keyboard and stylus.
What you're used to and what features you need will heavily influenced the process I guess.
