How the errors/debugging compare? From what I've read this is the main pain point with Nix where a more mature language like Guile should have a much better experience here. The article touches on this but I'd be curious of a more extensive comparison about this aspect.

Just a personal anecdote, but the errors from Guix are terrible. I had to reinstall because I couldn't figure out the scheme errors for my system config

		It's generally a problem with Guile. If you get decently good with Geiser or stare at the stack traces long enough, you can figure out the problem but I shouldn't have to do either.

Emacs + Geiser can do everything from a REPL in order to debug it. Emacs and Guile integration both come for free since decades.
