There's rumors that have been slightly confirmed that the 2022 anime is going to be a fairly straight adaptation of the original manga.
I think anime reboots that are straight adaptations of manga that already got a pretty good anime adaptation the first time around are pointless. I know the original
Urusei Yatsura TV series wasn't panel-for-panel accurate to the manga but the main plot points for the chapters that they adapted were almost always pretty much the same and the changes made with the anime adaptation were either because things that work in manga don't always translate to anime, especially when it comes to pacing, or because some of the shorter manga chapters couldn't even fill a half-episode segment if adapted straight, so some anime-original filler material is needed.
Even in cases where the anime started doing its own thing, and I'm especially talking about
Sailor Moon since it was adapting a manga that really had only just started and I believe Naoko Takeuchi only gave them a rough outline for the end of the Queen Beryl arc, which differs greatly from the manga, I often still prefer the anime version of the story. Many of the filler episodes of
Sailor Moon are my favourite episodes of the series since I generally prefer the episodes that are more slice-of-life with a funny monster-of-the-week at the end anyway.
In the case of
Sailor Moon, I at least understand the point of the reboot for people who do prefer the story from the manga and wanted the main focus to be on the overarching story, but there's not really the same overarching story for
Urusei Yatsura since even the manga was an episodic sitcom.
