Spending a lifetime learning img2img and using weeks to create a single artwork will always beat someone without experience who creates an artwork in an hour. There will be only a handful of people who will put in the time to become true masters of img2img. Everything comes always down to how much actual physical time someone is willing to put it. No matter how advanced the tools become, there's always a learning curve to mastery, which only a few people are willing or able to climb.
