Ask HN: Are alternative (oil, nu, etc.) shells usable as daily drivers?

Hello folks,

People using alternative shells (oil shell, nu shell, etc) as daily drivers, how is your daily experience?

I'm talking about a professional work experience, i.e. you use the shell as your daily driver at your workplace, not just for playing around.

Fish is probably usable, but outside of fish, is there any other production-ready alternative shell?
