>>112614113Out of all of them, I would recommend Infinity Train the most. It's one of the few cartoons series lately that can actually handle having some cartoon charm while having serious themes at play. In the other shows the characters try to use the fantasy world as an escape from reality, while in IT there's an urgency for leaving in both seasons.
Owl House only has two episode so far and it's definitely tonally goofier than Infinity Train and hard to say how it'll compare with Twelve Forever. Owl House has more dark fantasy aesthetics while Twelve is more of a weird acid trip.
Never watched Amphibia, but I might soon.
