Sans was harder for me, in the first run of course. Undyne had all her original attacks, except stronger and faster, so I knew what to expect. And cloudy glasses and ballet shoes make the fight easier, and I didn't really have to heal every time you make mistakes, however RNG is present. And "Battle against a true hero" somehow made me more determined to finish the fight.

Sans had attacks I didn't know about, I did see some of Papyrus' attacks. He removed invincibilty frames, which I rely on too much, and that personally made it harder for me. Even with the green soul's equipment, it can still be hard, however Sans' attacks don't really have much RNG, and require more memorization. "Megalovania" was like the boss music from Mario and Luigi partners in time, it somehow made me pressured and intimidated.
