Flown with both types and can absolutley say that there are few differences. Arguably an approved school graduate is likley to fit into a 73 slightly better than an unapproved graduate, but conversly nons tend to have a wider range of experience and so fit the Air Taxi role slightly better.
Once youve got 1000+hrs in GA its all academic anyway and as for the next year the only way to get the time is in GA which evens things out. Once your past that its irrelavant what school you went to but your last base check report.
Personally I prefer the nons but Im biased as I was one. As a B200 Captain the slightly more varied experience of the non is preferable.
I thoroughly enjoy this forum, although perhaps I should apologise for crashing it as Im no wannabe.
