I think we all forget what the MCC which is all about. Personally I'm choosing Simtech which is a very competitive price and from what I hear from past pilots who went there that it's done with experienced instructors who have worked in the industry for years.
Personally I think going to do an MCC on a complex full motion or whatever could be a disadvantage as you spend most of your time focusing on the aircraft and not what you're are really there for which is learning how to fly multi crew.
