Both are fantastic fun cars, in my experience the 7 is strapped on and almost worn the driving sensations being raw with sublime steering and that induction roar and devastatingly quick when required! But as others have said, not a car for pottering around in and less fun on our busy roads.
Whereas the Mog (both trad +8 and Aero) are more passenger friendly and subtle to a point, but with a hooligan streak just below the surface. The reception that a Mog always receives from everyone who meets it is pure enthusiasm and interest. (Even from the family who had the factory driven Aero "land" on their car and front garden. Who we met in a car park during Mog17.)
I do miss my 7, but I know which I would rather be making a road trip in - see below.
