I moved from JAA world to here in USA last year and working now a big company with FAA licenses. I have 18 years experience with European system, and when they got JAA regulations it went crazy. Regulations are same for everybody and all countries which are implemented those should use them equally. It wont happen.
Now, I have to say that here in FAA world things goes easier, but still in safe way. There are no any hassle with type ratings (when needed) or any other aircraft trainings. And what is important for individual pilot, this system is 5-6 time cheaper to have licenses like ATP and IR. I paid $8500 for IR ticket. In JAA system it will take maybe around 30 000 to 45 000 Euros! ( $40k -55k) Same result; I work IFR operations and like everywhere, companies gives you Initial (and recurrent) trainings before and between work.
I am happy,
