a.a larger flush volume
b.no need for a wax ring
c.fewer joints and a lower profile with easier cleaning
d.elimination of the trap

A one-piece water closet integrates the tank and bowl, so there are fewer joints to leak and a lower, smoother profile that is easier to clean. It still requires a wax ring seal to the flange and a trap. The choice is largely about maintenance and appearance.
