Sry for hype
Imo the F/A 18 is much easyer as the M2000 but thats more a feeling, and now the Hornet is EA. But thats a bit of advantage to be honest, becuase u can learn one system after the other.
Some systems might be a bit tricky at the moment but if u are a rookie u should start easy, start up,... fligh, get a feeling(thats really great in fa18) land and learn carrier recovs.
Sure u can nearly all of that with the m2000 too ( no carrier missions) but for me i just can say that much,... love at first sight. I got m2000, a10, ka50, 109, huey, viggen and non of these brings me so much fun. at the moment im in hospital and i count hours to fly again.
I think the 18 is interessting in so many ways. BUT REMEMBER its far from full release it is really EARLY ACCESS but still a great plane
EDIT:
And no matter what plane, take ur time for chucks Guide, it will really help and u dont neet to ask questions wich allready ask so often :)
