The flyer is one of the first boards I foiled on. It's a bit a matter of taste - anyone who likes longboards (I do) will probably like it, others may not. The big advantage over other foil boards is that it has a very nice glide when not foiling. In on-off winds where you're on the foil only part of the time, it can be much more fun. Last year at light wind races with ~ 40 racers, a guy on the Flyer 280 came in second in most races, ahead of some decent longboards like Equipe 2s. He was (and still is) an excellent longboard racer, though. Conditions were so light that he never foiled in the races.
When foiling, the board may be a bit harder to control than dedicated foil boards. Here's an example from (roughly) my 5th foil session:
My wife on the same board (she had maybe 2 more foil sessions, but learns faster than I do):
