Simulator training has its limits, concentrating on keeping all of the instruments showing the correct results. What is missing is the ability to respond when something goes wrong and the instruments show the unexpected. There is no substitute for proper training in recovery from unusual attitudes and this is missing from most curriculums.
Many years ago an aerobatics instructor spent a week taking me up under the hood, throwing it all over the sky and then saying "you have control" just as my breakfast was about to make a bid for freedom. Scary as hell but that week taught me more about flying than any fancy modern simulator could possibly do.
Ask yourself, when it all goes suddenly wormy could you figure it out without any outside reference ?.
