I would say eating fruits
Most fruits have juice of some sort so that way you are getting the best of both worlds in response to your question.
Plus you get to EAT and DRINK this way, so its another 2-fer
With drinking you most likely have a bottle or glass you have to deal with at the end.
With eating fruits, most come wrapped in their own container that is edible. No cleanup required.
With juice no one will ever utter the immortal phrase
Is that a banana in your pants or are you just happy to see me?
I believe this is conclusive and indisputable evidence that eating fruits is much better than drinking juice
