One thing to keep in mind from a solo traveling aspect is that you are going to get girls out on dates 10x easier in Medellin than the other two combined. If you want to kill 2 birds with one stone and go on dates to see the city and have company Medellin is the place to do it. The other two cities you'll spend all of your time just trying to game girls to get them out on dates. Girls aside all three cities are great.
