We only took from here the ferry to La Gomera
"Port of Los Cristianos for Sunset"
My Experience is Los Cristianos was very poor as we only went to the port, park the car, get the ferry to la Gomera and drive back to our apartment near the Sofia Airport.
But from what I saw, it looked like a typical holiday resort. I prefer the north of the Island, and If I come back I will stay at Puerto de la Cruz for sure.
