Wembley everytime. You only have to compare the Wembley 95 show to Giants 01, im not talking about the setlists (cos we all know they were better in the 90's anyway) but if you look at the crowd interaction. I know it doesnt help that Giants is all seated but Wembley is a much more prestigious arena famous for some of the best concerts of all time, ie Live aid, Queen and Queen tribute etc
