spent 3 months in all three, my thoughts:
Peru was the easiest to get laid in
Peru and Ecuador girls are same level of looks
Colombians are flakey and tend to have more princess syndrome, much more so than Peru or Ecuador.
Colombian girls looks will vary where you go, the coast was not anything special, other spots should have better quality girls for looks than Peru or Ecuador.
Of the the three places Peru was my personal favorite.
