Welcome to the Wannabees Forum
If you think about your question a little you will realise that very few pilots use more than one FTO on their way through and therefore are unable to give an objective comparison of which is the best school!
May I suggest that you read through a lot of the posts here and form your own opinion. You will also find a myriad of advice on select a school.
Good luck with your research
