Do not confuse industry professionals who teach advanced sequences (including IFR, airline multi-crew procedures and pressurised turbine ops in C90/B200/C550 type aircraft) with the "hacks" who do nothing more than lap the circuit in their ultralight/C150 all weekend.
In spite of my earlier comments regarding GFS, some (I'll concede "some" not all) of their pilots are amongst the best trained and professional aviators you will ever come across. Numerous airlines would seem to agree, as there are plenty of ex-GFS guys now flying heavy metal who never did their time up north in some clapped out C206 - and whose flying skills and command decision-making abilities are no worse off for not having any, how do you say, "real" flying experience.
