I primarily use Wunderlist, because it's truly cross platform. I can use it on my desktop, phone and the web just the same. I use it mostly for actionable notes...things I'm planning on doing something about at some point. It's more of an idea bank than a todo list, though, for me. For more free form note taking I'm using Rocketbook's "smart" notebooks (https://getrocketbook.com/ https://getrocketbook.com/). I can scan the notes to Evernote, and when the notebook gets full, I can easily erase the notes and reuse the notebook.
