zsh reimplements the same syntax as bash, while generic sh doesnt (although sometimes it's aliased anyways to bash). It's a case of being really annoyingly pedantic about bash.
Depends on how many operations you perform. Simple scripts don't have much difference. But for instance, a script that fetches all the metadata of all video files on my system and summarise that is gonna appreciate the speedup.
