I’d say PopOS with the relatively new Cosmic Desktop could be something interesting for you to try of you don’t really want to go into configurations that much. It has floating and tiling windows that you can switch easily.

They’re looking at it from todays reddit perspective which is much different to when reddit first started growing. I joined reddit about 10 years ago and it was still a little awkward to get into. But people got used to it and the platform evolved and it seems like most of todays redditors were not around at that time. Lemmy today feels more like reddit 10 years ago so it just does not appeal to many modern redditors.
