I switched to Niri at the end of last year after over a decade on i3.[1] Having horizontal scroll unbounded by my monitor size and workspace count unbound by the number of shortcut keys I have configured has been very freeing, and the graphical stuff is nice too.
My only remaining pain point is that its X compatibility layer, xwayland-satellite, does not yet support drag and drop between X and Wayland programs.[2]

I'm in a similar boat, but I've found where I once habitually put things in the same workspace every time and was able to trivially recall them, I now end up all over the place.
Also I've been missing scratch deeply.
I'm sure it's solvable with some diligence and config changes, but I haven't invested the time yet.
