It depends. While, IMHO, it’s easier to begin with case do, if the body of different branches of case is getting larger it’s nicer to break it into multiple functions. Plus multiple functions if fail - will give you better backtrace info on where to look at. Also, to me, it’s somewhat easier to read when the whole body of the function describes one path rather than keeping condition context in mind.
Or, just whatever is easier to read =)
