I started out using aisle seats and liked the flexibility of getting up and down. But, as I am young and don't need to use the bathroom that often (or can hold it well) I decided to try out window seats and I don't regret it one BIT. Like Gralistair, SCENERY. Oh yeah, I love seeing the scenery and taking pictures of it to bring back to my family who may never get to fly much. I love flying into the sunset or sunrise, it's just so gorgeous.
