Zeref would take this hands down. After all, this is the dude that accidentally kills everything around him without meaning to (quite a large circumference) and can OHKO/kill Fairy Tail's strongest human mage (Purehito/Hades) by pulling a simple Naruto jutsu/ Spike Spiegel "bang" combination technique when he was serious, angry and wanted to kill. Also, he's immortal. If he was blood lusted, Zeref would surely take the cake.

Unless Zeref is affected/distracted by the power of Mavis' loli/moe status, then there is no way she would win. Also, we haven't seen many feats from her; Fairy Sphere wasn't exactly her doing and her Fairy Tactician moniker was kind of trashed at the Grand Magic Games with Kagura intervening in the fight between Erza and Minerva.

Zeref comes out on top, unless Mavis is hiding something extra powerful up her sleeve that we have yet to see/experience. We do not know the full extent of their powers - for all we know they could be physical gods - but nevertheless, I would expect the Bishonen, that's regarded as Satan walking the earth, to win.

And more...
