I've tried Evernote, Apple Notes, the Remarkable Tablet, vimwiki, and I keep going back to handwritten notes on paper.

My current workflow for notes is: I take notes on the notes app on the iPhone or my Mac if I don't have my A4 Moleskin notebook handy. And then I transcribe the notes on the Moleskin whenever I can. Another recent addition I have to this workflow is a Brother VC-500W label printer. I use it to print QRcode stickers for URLs that I stick on my notebook.
