Dragon Fairy is still the better defensive typing, though. Being weak to things isn't as important as resisting them for walls and tanks (assuming you're not like Exeggutor status and weak to half the dex).
With that, you resist Water, Fire, Electric, Grass, Dark, Fighting, Bug and are immune to Dragon, effectively making it a potentially good Dragon counter/check as well.
That being said, Dragon/Water is no slouch either. 4x resistance to Water and Fire, and normal to Steel, while being weak to very little. It's also got great neutral coverage, which allows it to potentially tank a little better.
