Honestly, I always preferred Feysand over Feylin because of how toxic the relationship Feyre and Tamlin had was. Tamlin was controlling, believing Feyre to be nothing more than a possession that he owned and that she had no opinion, which is such a horrible thing. Of course he meant well, but he didn't see Feyre for who she was. Rhysand was always meant for her, even if it did break my heart to see the ship crash and burn.
But let's be honest, here. Both of them are Territorial Fae Bastards (points to whoever gets that.)
