My disclaimer is that I love bash. I write way too many things in bash. But eventually I go back and refactor the scripts into Python (or lately, Go) because I am so sick of people refusing to touch my bash scripts.

String munging in Python is so much objectively easier to read than bash. I would say that it's because it is similar to a lot of the more popular languages than the sort of cryptic parameter substitution bash provides. And if that makes it easier to maintain some automation, then its worth the effort just to use Python IMO.
