If just talking about shounens yea. Tho CSM when it gets to the best of pt 1 will be in competition. Also hopefully Mappa can put a better effort in Jigo's S2 and be more consistent throughout.
Demon Slayer is fun and animation heat. But it feels too generic shounen which isn't bad. The other members of the Demon Slayer group MHA, Fairy Tail and BC aint even in the same conversation. As the 3 Dark Shounens that I listed above.
Didn't care for CSM. Didn't find the premise interesting (come on man, a dude that transforms limbs into chainsaws?) and found the main character weird - I think I remember reading a couple manga chapters and dude was so spineless and some girl said she'd adopt him as a pet and had him on a leash or some shyt. I can't get jiggy with that. Then the anime came, I saw one episode and didn't like the artstyle and direction. I know that it's popular, but it doesn't appeal to my sensitivities.
Demon Slayer is nice, I like it - although with Demon Slayer, in some regards, it still suffers from anime old story telling artifacts like the ultra focus on Tanjiro and Nezuko, Tanjiro being framed as the second coming of Yoriichi, recycling tropes and arcs - swordsmith village arc felt like a recycled entertainment district arc with less tension etc. Side characters aren't developed or motivated to a satisfying degree. Shame because it has a good foundation that could have led to some amazing shyt, but largely it went the generic route like you said
I stopped reading/watching MHA when Mirio lost his powers, just woke up one day and my interest was gone. I've told myself I'll catch up with the anime but the one time I tried I fell asleep
Now JJK - JJK is piff throughout - you can see the HxH influences right away, a bunch of cool and motivated characters, tactical fights - gojo vs toji kinda reminded me of pre-time skip naruto fights like zabuza vs kakashi or itachi vs kurenai/asuma/kakashi where the focus is on bunshin feints, small scale jutsu and tactical analysis and execution - those are my favorite fights. shyt just speaks to me on a different level
