I'm a huge user of Spaces - I always have a minimum of 3 at any given time and have come to prefer one large monitor with spaces over multiple monitor setups.
I'm still getting used to Stage Manager but while I see it as having some overlap with Spaces functionality, for me it works best as a complement. My Spaces typically have enough windows open that there is a lot of triggering of Mission Control to find what I need. I love Mission Control - it's one of my favorite parts of MacOS (Windows has tried to copy it, but their implementation remains so slow that I don't find it a practical tool the way it is on the Mac). Stage Manager allows me to sub-divide my Spaces with apps that are often logically used together.
It remains to be seen whether I stick with it long-term, but despite some bugs, I hardly find it to be the dumpster fire the cynics make it out to be.
