Yeah, that's how I feel. They're both awful movies but I didn't walk out of JL completely P.O.'ed. I thought at least Superman was decent in that film, even if he was barely in it and I thought Wonder Woman ("Kal-El, No!" scene aside) and Cyborg were good. I walked out of BvS just disgusted at how my two favorite superheroes were treated; one was a mute with no personality and the other was murderous psychopath making Dick Cheney speeches. And my favorite supervillain, Lex Luthor, was reduced to a clown.
Really though, it doesn't matter which film is better. I guess I'd say that BvS objectively is a better film overall but they're both garbage movies that I never want to sit through again.
