The issue with that is that it is all vaguely shown in show. The writers even were asked about Regina's light magic and they sort of gave a "meh, it's all the same to us" kind of answer. I do think though those people are the top rung, except Lily who is a novice.

6x13 showed Rumple as normal DO's biggest onscreen feat to me. He pretty much exploded the entire Ogre army that was left (unknown number). That likely tops Jafar disintegrating a dozen people (although he also had possessed Amara's power in some capacity).

Likely as the show seems to be rounding out it's just (of those of season 6b):

Rumple

Experienced witches (Zelena, Regina) Emma on a really, really good day

Zelena on a bad day. Emma on a good day.

Emma normally.

Regina on a bad day. (Regina's self-confidence hits her hard because she often has a bad day these days)
