Area pays more, but it's the same thing every day, by no means as much variety as ADC where you see the aircraft and get to appreciate more readily why things go wrong when they do.
Each to their own, there are job specific skills in both trades which are not easily transferable to the other, it's only those who have done both who would be able to appreciate the fine dividing line.
For me, it's ADC every time, area is a dark art practiced by those who are paid a lot but only allowed to emerge from the depths for a short while every month or so - even then they are hung upside down in their wardrobes each night.
