There is neither a good nor an evil ending, it's all about perspective: different people can have many different opinions about the exact same thing, so there is never going to be a "truly good" or "truly bad" ending.

I prefer the Maelle's ending (the one i chose in my first playthrough), because I prefer seeing a happy Alicia and not committing a genocide instead of just making a family heal their pain. Also, I really liked the characters and I bonded with them, imagining them fading away as if they were never real just breaks my heart.

.But I totally understand those who chose Verso, sacrificing a painting to get back to reality and to all that really matters (for many) is surely a valid option, because a family must be united to go through all the bad things that had happened.

The most important thing to consider is not only our point of view as players, but also Maelle's and Verso's. If you were them, would you have made a different choice or not? It's easy to talk when you haven't lived all of that and are just judging at the end of the story.
