Most will try and push a trainer jet but if you do the research you will find some good scale jets are easy to fly. Like anything landing is the hardest part. F-16 flies like a pattern plane(my opinion), and that depends on the scale you get.
The A-7 wouldnt be bad either, Lowell aka Jet time has one and from what he said it flies similar to a f-16
Everyone I have talked to has said the same thing about the F-18, the super hornet seems to be harder than the old version.
f-16, f-15, A-7 would all be good ones, it all depends on your personal ability. I went with a 1/6 scale f-16 for my first turbine, and have enjoyed it. Good luck with your venture
Jet time can tell you about the A-7/F-15/F-16
Falconwing seems to be a specialist on F-16s(had them all I think)
