Rumble-Rumble Fruit for me.

I could charge my phone and power anything at any time with the Goro-Goro no Mi, I'd take that.

It pretty much solve world hunger with woods, pretty much solve most problems with goro, or be a dinosaur.

Woods Woods fruit without a doubt. Imagine being able to create nature wherever you go? You'd possibly be a step closer to stopping world hunger and help create new environment and restore lots of lost wildlife. And you don't have to eat either and feed off on only sunlight and water which is a W imo.
