What do you think is the most attractive accent and the most annoying?

When I first moved to Texas from New Jersey it seemed like as soon as I spoke people backed away. I felt like an alien. Now it’s all watered down and I think I sound “neutral.” What accent could you listen to all day and not tire of it? Which one annoys you? Maybe you just can’t understand what someone is saying. Or you may associate the accent with a negative situation. I think New York accents sound cool unless they sound too rough. Does that make sense? I don’t care for southern accents at all but I think most people like them. I like the way Mexicans sound; and the English sound beautiful but “cockney” is unintelligible.
How about you?
