All of them are one of the best and more serious schools in Europe. I believe if you decide to any of them, you will be well served.
Bartolini count with 1 year waiting list. If you are ready at any moment you might be lucky and pick a spot from someone that gave up but the current waiting time is around 1 year. I believe is more of less the same situation for Diamond but maybe other people can conform this.
Good luck
