So after this season aired, here's my ranking:
1.Season 1: Awesome teams, awesome destinations, Ferna & Fran
! ... Perfect season!
2.Season 3: Teams were too nice (in a bad way), boring destinations, but it is still better than season 2.
3.Season 4: Mix of good and bad teams, unfortunately bad teams made it to the finals (WORST WINNERS EVER!!!), also boring locations.
4.Season 2: Awful teams and the most interesting ones went home early (Susy & Stefany, Mauricio & Mariana, Roger & Omar, Jelkin & Javier (i hated them, but they were fun to watch) and Edisons), Amazing destinations but the editing was too poor to enjoy them!
