In some cases, 20 gauge shells have better sectional density which may result in slightly flatter trajectories.

One example is Brenneke's 20ga 3" magnum slug. It weighs a full ounce (like many 12ga rifled slugs), but it, of course, has a smaller diameter which may improve aerodynamics and result in better penetration. I suspect similar examples can be found among sabot slugs.
