I'm not saying that powers aren't roughly equal. But that's in context. Giving a fighter an area-attack at range is a much bigger deal than giving one to a wizard, because the wizard already has them; the fighter probably doesn't.
So while that area attack spell might be mechanically balanced with a fighter power of the same level, the fighter may well feel that it's worth more, because it lets him do something he couldn't previously do.
This is a mixed bag of course. Even if the fighter's equivalent power is of "equal power level" to the wizard's ranged AoE, as you said it comes down to Perceived Value. In this case is it better for the Fighter to gain a power that is specifically geared to do what a Fighter does (STR based attacks in melee)? Or is it better to give him a new "trick" where he can he lob a ranged AoE 1/encounter? Some will argue for both sides. I personally think that giving the fighter an option to do something when he normally couldn't (since most fighters end up twiddling their thumbs until they can enter melee) is a better option, which of course proves your point.
