I don't have reason to believe FE is any worse than other third parties, but in general, once things go wrong with a booking, the fact that it was booked through a 3rd party seems to slow down getting problems resolved. I guess we've all had an experience where the airline sends us back to the third party when there's an urgent problem. When I was using a credit card rewards portal to book our post-cruise flight, I almost went with the discount airline Westjet, but found it was impossible to get a question answered as Westjet's phone tree kept telling me they wouldn't deal with me if I was booking through a third party (and I was sure the credit card portal would not know the answer). I ended up going with a Delta flight for a few more points. Maybe some airlines cope with 3rd party booking better than others.
