The NFC only just started their integrated course. So the only people with experience of that will be the current students. So I doubt you'll get much information on that situation.
But they've trained many a pilot over the years, including me, (partially). I never had any real problems with them.
Don't know anything about Atlantic. Their integrated course is brand new too. But the have a good reputation.
If it's a choice between the two I would pick the one you're closest too.
You didn't mention PTC and I won't either.
Agree on the selection tests. They're a marketing tool for one thing and for another they're a way of eliminating complete duffers who would make the school look bad if they got onto an integrated course. I spoke to one senior Instructor at a school and asked him why they had introduced a pilot assessment. He told me it was just because the other schools, sorry 'Flying colleges' had them and they had to compete.
