i'm going to continue using it for simple projects. really the only thing that i strongly dislike is the GTK3 bits (not the fault of Horizon at all, but very much a thing that causes friction for me the entire time i'm using it)
it seems like you can import KiCAD footprints, and it's reasonably easy to procure those nowadays, so i think the lack of devices in the pool isn't that big of a deal. i'm not sure whether there are any facilities to e.g. generate BGA footprints, but if there aren't i could just use KiCAD scripts for that
