Wrong.
Rainbow is nice. She risked life and limb for others. And was a sister figure to Scootaloo and Fluttershy’s as well. And more respecting with elders with Applejack.
Twylight is the selfish one. The Marer Do Well and Walking Dead hoaxes, the puppeteering of the swamp and cheerleader incidents, the Lesson Zero Incident, betraying Pinkie in a quiz, trying to prove Pinkie wrong this almost getting everyone eaten by the hydra and parasprites, her doubting Pinkie with babies, her obsession with returning an overdue book to preserve her picture as top book keeper, her dumping Moondabcer’s party, producing Dyscord and Capper for being non-Equestrians, her trying to split Starlight from Trixie, her presiding Zecora, her neglecting Flurry Heart, her betraying the CMC without clues, her using others so she can rob Queen Novo, and neglecting her human pals. All to preserve her image and suck up to Celestia.
Applejack is a workaholic. And overbearing. And an ageist as prove with Applebloom when she babies her instead of accepting her own error, and treating elders as weaklings.
