Not for me, it isn't. To me, it feels kind of stiff, like a looser Triakis. I guess it just depends on your playing style. EG-X turns just fine for me, and I sometimes have trouble when using G45. That thrust probably affects the feel of the thing when turning though, so maybe that's why you feel that it's looser (I'd imagine this would affect airbraking more than regular turning).
So IMO, the handling stat should just be seen as a kind of "review" somebody's done of the handling, rather than a real "stat".
