Darlifra and Plamemo aren't similar at first place but what I can relate is the similarities teams work on both shows. Both anime has their partner themself in different association and works together until the end even though some character aren't.
After all, I don't know how to recommend Darlifra just because of (one) aspect and my opinion but it is up to you to decide it.
