"Better" is a matter of opinion, but it certainly isn't a "margin note". Rarbg was one of the most popular torrent sites in the world. Torrent Freak puts it as #4 most popular in the world, ahead of The Pirate Bay, though I am not sure of their methodology.

Of those most popular sites, I think it was by far the best. It offered consistently good encodes, with about the best achievable quality for a given file size, in a variety of formats and resolutions. Its files were well-organized with a user-friendly browser and a wealth of metadata. It was possible to quickly find a good version of anything not too obscure.
Compare to TPB, where searches just vomit a page of often-mislabeled files the user must comb through manually. Compare to YIFY/YTS, which uploads bitrate-starved "HD" schlock that looks worse than rarbg's 480p.
