I wish the project best of luck, though I feel that it is going to take them years in order to reach parity with KDE, which combined with Qt took decades to bring to its current feature set.
KDE is great, but it's enormous. If you like it, go for it. This is almost more for the OpenBox or perhaps Gnome folks. Minimalists. Curated, opinionated, fast (yes KDE is also fast)
I started with Cosmic on Pop! 22.04 which was fine but then I wanted to try KDE and installed it and stayed with it after I found it to more customizable as per my preferences.
At this point I feel like I probably should have just used Kubuntu instead and be up-to-date (Pop! is still stuck at 22.04). Everything works though and I am too lazy to risk issues / dealing with time spent on setting everything again.
