I've always wanted to check out any of the comics/mangas to see if the franchise is really as cringeworthy as the internet claims.
I don't know the manga, from what I see it looks weird, but more in a kiddy way than a cringey way.
There's two (main) comics. The British 'Sonic the Comic' by Fleetway, which I've heard is pretty good but never actually read (and it's from some time ago), and the Archie Sonic comics, which include a lot of great stuff (some rough patches, but lots of good stuff) and is a very long running series that does a lot with characterization and worldbuilding, and has side-comics like Sonic Universe, which normally focuses on characters other than Sonic himself and really fleshes things out. There was one continuity reboot in that one, but with enough carry through to still feel like the same beast. The writer Dakka and I gush over, Ian Flynn, started at issue #160.
Secondary comics not in continuity with the above include Sonic X (which I *think* was supposed to be good but, again, never read), and Sonic Boom (short-lived, same writer as the main Archie Sonic writer, has a lot of the same humor as the show).
When people say the franchise is cringeworthy, they're probably referring to some aspects of the online fandom. Which, yea, there is *totally* plenty of cringeworthy stuff out there and you should not look for it.
