Easily: Skyburner’s Oath Aeon Exotics Salvation’s Grip In that order respectively for me. Anything else that people put on there are just straight up wrong tbh. I can find niche uses for nearly every exotic whether it be PvP, or PvE, or Gambit. Even Aeon Exotics and Salvation’s Grip have some value, even if very little. But Skyburner’s Oath? God... you’re wasting your exotic slot for what is objectively a downgrade. Yes there are plenty of exotics that are incredibly niche, or weaker versions of other exotics, or just generally weak, but I don’t think there any exotics except for Skyburner’s Oath where no matter the situation I’ll always choose a blue over it.
