Alex beat me to it.
However, I'd like to add something. When I was thinking of choosing a groundschool, I got some excellent advice from Send Clowns. (SC - not sure I ever really thanked you properly for that!) At the time, he was an unemployed groundschool instructor, and in the perfect position to give me completely impartial advice.
If you're looking for a residential course, then you could do a lot worse than listen to Alex. He's in the business, probably knows it as well as anyone, but since his school doesn't offer a residential course any advice he gives will be about as impartial as it gets.
But his point about different styles of school, and the fact that they attract different types of student, is the main thing - go with whichever one makes you feel most comfortable.
Good luck!
