I've been using nushell for the past year, and I love it.
For a while I kept bash as my login shell and had nu as my default command in tmux. This had the advantage of allowing a bunch of environment setup to run in bash and get inherited, which allowed my overall setup to be more vanilla (and also nushell doesn't have any kind of job control, so something like tmux is probably a must).
About two months ago I promoted nushell to my login shell. In hindsight that was probably more trouble than it's worth, but I have no intention of changing back.
I now keep a very minimal bash config (~10 lines total) for when I inevitably need to shell into it for some reason. That doesn't happen very often, though — a quick look at my bash history shows that I'm mostly either running stuff interactively which assumes bash, or using it as a repl while working on scripts.
I wouldn't recommend nushell to anyone without a decent background wrangling posix shells, because that's not going anywhere. I've had to reverse engineer a bunch of shell integrations for things like package and version managers, most of which assume bash/zsh/fish.
I don't resent any of that work, because I'm in my shell all day, and the expressive power of nushell is so far ahead of other shells for the kinds of tasks that I'm doing in that environment. I won't try to convince anyone of this, since the question was about suitability for daily use. If you're into it, you're into it.
I'll just add that nushell in particular rewards daily use, because as a language for writing your own custom commands, it has a way of quickly building momentum once you get going.
