I tend to ignore manuals, but two exceptions stand out to me. The Civilization series always continued making decent in-game manuals, or maybe 'wikis' is the more appropriate term. And while I would say that the manual for bash and python are decent, if inconsistent --- I wish bash manuals would prioritize frequently used arguments or flags --- R has really taken things to another level. R is probably the only software where my first instinct is not to google it, but to actually look at the documentation, because it is integrated so seamlessly, and because it is well organized: parameters at the top, examples at the bottom. And R's cheat sheets are also something else: https://posit.co/resources/cheatsheets/ https://posit.co/resources/cheatsheets/ . I had some of those laminated, because they are just such a joy to look at and browse.
