It's a no brainer to assume that Logias are going to be the strongest fruits by far.
Awakened logias will atleast be able to replicate what others - most likely non awakened users - already showed:
1) Turning the environment into your element or atleast spreading your element around, while you are able to mold with it- Monet and Croc.
2) Create something like an avatar form- Enel's Amaru, Monet's snow harpy form
-> I'm lowkey thinking Monet was awakened
That stuff was already shown and especially point 1 should be incredibly powerful and tricky to encounter. That shit is going to be everywhere, while they warp through it at high speed and spam attacks at the opponent from wherever they want.
And point 2 will be insanely powerful for guys like Smoker, that can clad their element into solid CoA hardening. Guys are going to catch these gigantic smoke hands.
A guy like Kizaru for example should easily be sble to channel big amounts of light masses into a single spot - similar to Ace's Dai enkai - in order to create whatever monstrous attack is going to result from it. I don't even want to think about it.
Oda better not have that man awakened
