perhaps, against nature of this thread, but I switched to a remarkable digital notebook a while back, and love it. it has totally replaced the notebooks I used to keep.
its feels enough like paper to be a pleasant experience to do things like sketching on, and immediate enough that you don’t have to think about it (unlike my experience with ipads/computers which like structure etc) … (*)
I arrange things as a number of bullet journals based around loose ideas, like projects or explorations.
of course, unlike some here, I don’t really have a big attachment to nice pens/notebooks,
I used to use cheapish notebooks, with a 2H pencil, and that’s all i needed to be happy
,
as I just enjoy the process of taking notes, a way to brain dump ideas - and move on.
I find it amusing that once i write/draw something, I rarely need that note again, but the process is some how liberating - also i find if Im procrastinating - writing/sketching ideas can be a good way to kick start me into action 
(*) actually, I weirdly/irrationally felt that my notes/scribbles were some how wasting paper, and didn’t like the whole storing them and finding them when i needed them - nor the idea, that they could be lost.
so, apart from the backup, i don’t really use any non-paper like feature - i only tend to read on the tablet, i dont use OCR - rarely use it for PDFs etc.
its expensive for what it is, and many seem to struggle with the fact it is just a digital notebook (so doesn’t have tablet features) - but its worked out for me.
