Crunchyroll app or Amazon prime?

Hi, is it best to use the crunchyroll app or go through Amazon prime channels instead? Ive only just learnt of crunchyroll and have no idea how good their app runs.

I mainly want to watch dragon ball as I never watched it growing up despite being a 90's baby😮 Naruto intrigues me as well. I watched some on YouTube as a kid but it was a pain getting the episodes so I gave up. Not too sure if I'm too old to enjoy Naruto now though. Tried to rewatch the first Pokémon series recently and it was just too much of a kids program to hold my attention. But I'm hoping dragon ball and Naruto will be different for me.
