You think? Admittedly, I'm not super familiar with it, but from the pdf I have I'd say the writing is fairly clear, the layout keeps topics to one or two pages (something 5e still can't manage to do), and at 60-some pages is a complete (dungeon crawling) game with a sample adventure. Granted, there is a reason that OSE has value as a more efficient presentation of these rules, but compared to the mess that is AD&D, I'll take any of those basic sets.The Moldvay Basic set is a disaster, not particularly better organized than the OD&D booklets.
(And yes, people love it, but it's by no means a paragon of good design or marketing.)
I started with the 1991 Black Box, which is designed around teaching the game and does a great job on that account.
