It is not as simple as that IMO. I usually take into consideration other things as well, such as aircraft types/seat types on a given route/deal, mileage earning (depends on which FFP you credit the flights to) and how easy it is to position to the departure point from my home airports (that is, how convinient it is and how much the cost is).
So I'd say you really need to figure out for yourself whether deal X is good or not.
