Thumbs up from me for ACS. I did my CPL, Multi/IR there in the middle of winter. In holds at FL80 covered in ice will really sharpen up the skills. In terms of what it did to help me get a job, i finished my training Dec 13 and in the following year i had three interviews, one which landed me a UK based airline on a heavy passenger jet with no type rating costs. Take from that what you will.
I did my MCC with some people who hadn't trained in the UK. They were from Iceland, India and Poland and from the first sim session, you could tell that their skill levels were no where near those who trained in the UK. Obviously you get out of your training what you put in, but that only goes so far. It depends who is training you.
