Women choosing the same type of guys is a myth It's a very specific myth the "loyal losers", as you called them, choose to believe. If there's one thing I've learned from the AWDTSG group, it's that most of the potentially cheating guys that get posted are very average-looking men. Not super attractive, but not bad; just normal guys. More often than not, some of the women would delicately point out at how do regular guys could get much more attractive girls, and how do those men date to cheat.
Most women don't care about superficial traits. Some do, but those are either very shallow people, or not very smart ones. Sure, we all have preferences. One thing I can say is I, as a woman who doesn't care much about a man's appearance, immediately get turned off by messages like the one above.
