Being manaless is not necessarily an advantage.

If you use health as a cost, for example, you are just bringing yourself closer to death, the more you cast your spells. Although every champion with health costs have natural ways to restore health, those usually are not enough and they must still itemize for sustain, which limits their buildpath and their build potential. Speaking of which, itemization for them is already limited by the fact that they can't use items with mana. Well, they can. But it is very inneficient. Vladimir, for example, has amazing synergy with CDR, but there are very few AP items that offer CDR and do not have mana or mana regeneration.

For energy users, the problem is that energy does not scale as well as mana, and it is easy to run out of energy during a single rotation. And once again, it limits their buildpath. Not as much as health based champions, as energy users do not necessarily have to itemize for sustain, but they are still limited by not being able to build items with mana. Also, they are limited by the fact that if they build CDR they just run out of energy even faster, and thus, they do not benefit as much from CDR as mana champions.
