Yes, pen & paper notes always. I consider myself a techie, but when it comes to learning or remembering, 100% analog, all the way.
As for the why, it’s a bit hard to explain, but the sensory experience of writing - the feeling and sound of the pen or pencil gliding on the paper - and the fact that I write more slowly than I type, which helps me sit with and process the infformation for a bit longer, really helps cement the info in my head.
