The most interesting comparison for me is that classical Athens left us philosophy, maths, drama, commedy, poetry, political intrigue and organisation. If Sparta had any of these aspects they have not come down to us. Pretty much all of western philosophy is an addendum to Aristotle.

Can't remember who was the Greek author who said that, even if Sparta could beat Athens, nothing would remain of the former while the latter would be remembered for eternity. He wasn't wrong
