I personally use a combination of Notion for collaborative notes/tasks/whatever, bullet journal for daily notes/tasks, and a markdown based zettelkasten for knowledgebase-type stuff. There's a fair amount of duplicated information, but both Notion and the Zettelkasten or easily searchable, and it's trivial to copy-paste between them.

I really like the paper method for day-to-day stuff, but for research or work-related notes, I simply can't write fast enough to keep up (particularly if I'm trying to capture info from a meeting), and the lack of searchability means I can never fully rely on paper notes as a means of retaining information long-term.
