Hehe that's funny. The most common criticism I've heard of AFT is there isn't enough text, and if you haven't flown commercially and IFR before, then there probably isn't enough waffle for the point to sink in and pass the exam.
ATC will waffle more than AFT...
Rob Avery might have a bit less waffle and more diagrams for the likes of flight planning, but also tends to round off too much occasionally getting the wrong answers in the exam.
Heard good things about Gavin Seacombe... but again, that was because he provided more information than AFT, so probably not what you're looking for.
