If you had to pick one, would you take a Sten MkII or an Ingram M10/9? This applies specifically to the guns in their original factory configurations; no Lage products allowed! It's hard to come up with a mass-production SMG that isn't obviously better than a MkII Sten, but the stock Ingrams might make the cut...the MAC is a more compact package, but has even worse handling than the Sten in some ways (which is a remarkable achievement!). So if you have to pick one, which would it be?
