Promised Neverland has been terrible for awhile
I don't have time to fully deconstruct every series you listed here, but to quickly summarize...
I can't say I hated the last couple arcs, but that ending? Yeesh. Even so, it was at least something to look forward to.
I walked away from the Jump Start chapters confident it was destined for the axe; naturally, I ended up some heavy crow. As a means of penance, I've reviewed the first three volumes for VIZ and while it's improved, its remained thoroughly average. Shame because I dig the message it's trying to share and it has some fun humor. The fourth book is sitting in my digital library as we speak, but I'm fearing this'll end up as another Black Clover where the appeal flies over me.
Casually enjoy, although my engagement started dropping during the Princess Iron Fan play. (Dragged too long for my tastes)
Rocky start aside, I ain't about to contest what's easily the funnest manga in the magazine today.
Not my cup of tea, but I acknowledge and respect the talent behind it. I just wish I liked the cast.
I'm all for anything with obvious One Punch Man influences, but I recall the opening chapters being trying
really, really hard to be funny and it fell flat for me. Caught the last couple chapters and it's transitioned into a battle manga now? Don't care for the art, either.
Again, this'll have to do some heavy lifting to wash out the awful taste of the opening chapters. Out of everything I've dropped, this and Mashle might be the most likely for a second shot, but I don't exactly have high hopes. We'll see.
Now this I can get behind -- the concept's silly, but it
is attention-grabbing and I'm already looking forward to how the protag'll get himself out of this latest jam.
I'd elaborate on everything else you didn't mention, but as far as stuff I do enjoy: Haikyuu's already set to end (and even then, I'm not a huge fan of how they initiated the timeskip), Yozakura's a humbling example of a mangaka going back and diligently researching the fundamentals of manga/comedy, and We Never Learn's cute whenever it's not flaunting teenage asses/chests in my face.
