If you asked me what I thought I would say sans would be the hardest because fighting him is just pure hell and I'm going to give you why if this was a actual fight not semi-bound to game rules

Reason 1: sans is literally impossible to hit, Toby just wanted the game to end... think about I

Reason 2: even though he only has one atk his dps tops at 40 whereas even at lv 19 you only have 92 hp (this is game technicality but I used it to show how much dmg he can actually deal)

Reason 3:this is more of a theory than a fact but I would believe that sans is holding back because he is not as angry as he is disappointed in you hindering what he is capable of

Reason 4: while he may only have 1 defense it is shown that he has incredible amounts of hp because when you hit him you deal a insane amount of damage far more than undone the undying could ever tank out and sans doesn't die instantly and still lives (for a moment at least)
