Personally I'd prefer to have to learn no shells at all, but since that's not possible I'll stick with the one that's most commonly installed, which is bash. Similar feeling with an editor - vanilla vi instead of learning and depending on a slew of fragile extensions that only work on a personal laptop. If the challengers supplant the defaults on servers in these domains at some point, I'll learn them then.
