Ask HN: What shell do you use?

There's a couple different shells available at the moment, the most popular being ZSH[0], Fish[1] and Bash[2].

Which one has your preference? And how do you deal with different environments and shells (e.g. SSH into a server and you're using Bash i.o. your own preferred local shell)?
