I like the first town they leave from, and the look of area around that part of the world. Also, the big 'ole field where you ride chocobos is pretty too, so that might be my favorite visually. I like Luca too though. I hate the location where Tidus first arrives in Spira and meets Rikku and gang. Maybe because it's ugly or maybe because I think that section was a bad boring choice, because for me the game does not even start until you leave off with Yuna and company. Oh and ick to Thunder Plains
