Merlin and Morgana are on the same level, with a slight edge to Merlin. In recent and previous episodes both have demonstrated powerful magic, but both have also shown that under the right circumstances their magic can be defeated. However, Morgana is very proud and this is her downfall. Also, Merlin is still constantly worrying that he'll be discovered as a sorcerer and this is his downfall. On the other hand, if Merlin and Morgana ever got into another magical one-on-one like they did before, Merlin would win like he did last time. I would have to say that while both are on the same level for now, Merlin will eventually surpass Morgana. As a side note however, I find it weird that Merlin the most powerful warlock (in later years that is) is not powerful enough to stop Arthur from being killed by Mordred or even save Arthur from his mortal wound inflicted upon him by Mordred. I mean if you're going to be the most powerful wizard then you should have the power to both stop someone from killing someone else and the ability to heal a mortal wound. Anyway, moving on. As for Sigan, since he is (or would it be was since he's dead?) older than either Morgana or Merlin, then naturally he would be the most powerful sorcerer as he was born during the time of the Old Religion and thus had years of training and honing his abilities out in the open. Also, Gaius said that Sigan had the ability to change day into night and reverse the tides. It was also rumored that his spells helped build Camelot and his powers became so great that he was able to immortalize his soul. So, yeah, it looks to me like Sigan, even in death, holds the title of the most powerful sorcerer ever...at least until Merlin gets older.
