ok, sans is weaker than undyne without a doubt, I wish sans was stronger tho. sans is better at strategy than undyne, but power is what matters. Undyne would win, and swap papyrus has the same stats as sans since it's just the characters swapped. They're lv, exp, and what not has changed to the character they take the role of. So swap papyrus would put up a good fight like sans but lose. -fell papyrus (cleetus)
