Well, yes, right now there are very few reasons for doing the FAA IR unless you already own an N-reg plane.
But then you have powerful reasons for staying with it:
A transfer to G is going to cost between £5000 and £10000 and that is if nothing goes wrong.
Especially if it is a "nice" plane, and the majority of N-reg planes are indeed "nice" (which probably doesn't help the politics of envy angle...).
And EASA is not currently proposing kicking out N-reg
airframes (it would be extremely hard to do, as others have found before) which is yet another reason why continued N-reg operation is worth examining closely.
We shall see what happens.
