Manlet is worse.
At least if you're ugly men won't belittle you. Half the population will still take you seriously. But manlets? Dude nobody likes manlets and not even other manlets. Napoleon conquered all of Europe, HE CAPTURED MOSCOW, and the first thing he's thought of in popular culture is as a manlet.
In WW1, the fate of entire nation's at stake in a cruel battle to the death, manlets were seen as so subhuman to be unfit of the dignity of the ultimate sacrifice. Nation's would rather lose than put a manlet on a monument in the center of town.
And it's always been this way. Throughout all time. It isn't a new phenomenon with Tinder or the sexual revolution...manlets have always been seen as less than human.
