Kimetsu no Yaiba is probably my second favorite currently running WSJ manga after MHA; I'm not counting One Piece since that series is now basically exempt from having to worry about competing for rank (not that it ever really ranks particularly low on any given week). That said, I'm going to be starting The Promised Neverland soon enough, so that could potentially usurp it and MHA since going by the premise, this series should really be up my alley.
I recently caught up with Dr. Stone and Robot X Laserbeam. Dr. Stone feels tonally very similar to Eyeshield 21, in that the plot is something that you would expect to take itself very seriously, yet the delivery is intentionally over the top, both in terms of its humor as well as its more genuine moments. That worked well for Eye shield 21, but admittedly feels a bit awkward with this set-up. That said, the general impression that I have so far is leaning more towards the positive side, so I'll be sticking around to see how this series plays out for at least a while.
As for RXL, firstly I just want to commend Fujimaki Tadatoshi on coming up with the most awesomely misleading title for a manga series in recent memory. Clearly "Roboto no Golf" wouldn't have been the most attention-grabbing thing out there, so he had to spice it up somehow.
As for the manga itself, it's pretty entertaining so far. It's nothing atypical for the genre, but even given how Tadatoshi clearly lost momentum with KnY after about the first two-thirds, I have to give him credit for understanding sports manga story structure well enough in order to set up key characters and get you invested in their development and growth fairly quickly, which is a lot harder to do than it sounds. That said, the one thing that I could see backfiring on Tadatoshi is how clearly overpowered Roboto is. I have no problems with the main character being a genius at whichever field they compete in. That said, if they are doing this well against top-level players this early on, then the series runs the risk of getting tiresome and predictable really fast. Both Food Wars and Black Clover are currently facing that very problem, IMO. Occasionally an OP character can work if the series is high-stakes like Akagi, or a bat-shit-insane comedy like Yakitate!! Japan, but since RXL is comparatively more tame and serious, it is a bit worrying to see how godly Roboto is this early on. That said, despite my distaste for where Kuroko ended up, and how much I loathe the spin-off, Tadatoshi has still produced more good content than bad, in my eyes, and the good stuff shows that he has some genuine talent up his sleeve. If his editor guides him properly, this could be a pretty fun sports manga in the long run.
