Symmetry/clarity.  I like case statements, because they list out all the
cases, and the compiler checks that you didn't forget any (so long as
you don't say "others"), so the reader of the code sees exactly those
cases.  And it's order independent.  With an if statement, you have
to compute in your head when "else" means.  No big deal in this case,
of course -- it's a bigger deal when there's a chain of "elsif"s.
