I am not sure who is older, the only thing I feel Papyrus is more mature than Sans.

Sans is powerful and often use of his ability like telepot, time skip.

Sans fear memory lost, cannot stand not using violence to reduce the possibility of world erased, and fnally realize he's under the illlusion of control.

''Papyrus is powerful and feel happy not using his ability. (He knows about telepot, time skip)''

Papyrus feel happy and don't mind about memory lost.

They are awakened guys, death means nothing to them. They know this world is a puzzle, their purpose is to give hints to the one who want to play, however, Sans get lost in the middle.
