1. Compliance to the letter of the SQL spec.
2. Ability to define a maximum length, if you happen to feel the need to
impose a specific maximum length. (If you don't have a good reason
to impose any particular max length, this is a minus not a plus,
because the spec says you have to pick one anyway.)

It's a loser on speed because of the extra cycles spent to check the
max length. Other than those cycles, there is no difference.
