This looks super smooth but I wish there were a floating-first version. All of the notable standalone Wayland WMs I know about are tiling-first which doesn't work well for me at all.
All I know is that I don't like the trend to moving controls into the title bar, making everything like Microsoft Office where there's so much crud in there you have to play Minesweeper to find a few pixels you can click on if you want to actually drag the window and not do anything else.
I want something that looks more like FVWM or even IceWM, a perpetual late-1990s vibe.
And the wayland compositor hyprland does support floating windows like any other compositor. Though I agree that if your comfortable with no/simple tiling, using Gnome/KDE/other DE's is likely your best bet.
