There are several benefits to using a sealed abstract class as the base of an algebraic data type:

it is faster
Java interop is cleaner
it is semantically clearer (an abstract class can't be mixed into multiple classes)

The disadvantage is we have to introduce another concept (abstract classes).

This will require quite a bit of rewriting.
