Personally, I find Papyrus to be older. The relationship that the brothers have is strangely similar to the bond I have with my sister (I'm also female). Im the oldest sibling, taller, kinda naive, and I'm not the best when it comes to decisions. Not all older siblings have to live up to it's stereotype: to be the responsible one. All of sans characteristics may point to him being the more mature of the two, but that doesn't give him the title of older brother. He's just a nice guy who cares a lot for his family :) Papyrus on the other hand may act aloof and naive, but he seems to know how dark the world is and still attempts to help and fix it. That's not a trait I find younger siblings to have. They may want to save the world, but I don't think they truly know how evil the world is. Papyrus knows and he still wants to help.

Whatever the decision, in the end we all have our own perspectives and biases. All of us come from different backgrounds with different ways of seeing things. It's just up to preference on what you want to believe.
