The only other thing to take into account if you opt for area is, if you ever have the desire to leave NATS your UK options are extremely limited with no aerodrome or approach tickets.
Personally, I'd do the aerodrome and approach if at all possible, that gives you the option of going to work at an airfield and/or doing APS at Swanwick if required.
That way you get the option of seeing the real aeroplanes, finding out where Gonzo really does go to oblute and/or working at Butlins.
Why anyone wants to indulge in the dark art that is area is beyond me but each to their own.
