For me the #1 advantage of FF is shallow DOF (isolation); and if there was a cheap option I'd go with 6x7. Sensor technology will always improve as well as 'special effects' and FF seems to move at a slower pace so from a technical perspective of sensor technology FF (and larger) can be better but there will be periods between leaps when it is less so.
