That depends on how... discerning you can be. Personally, I'm not to the point where many of the subtle things are even noticible.
It also depends on how you've got your Evo set up; the stock Hirobo paddles have removable weights, so there's quite a bit of room for variation out of the box.
That being said, I've had a fair amount of luck with the Dolphin (even made a skin that sorta looks like my Evo). Pete Niotis has a couple of tweaked G3 models which he claims are about right for most .50 class helicopters (based on the Dolphin). (He posted them on RunRyder too... thanks, Pete!)
Beyond that -- I can't say; primarily because (as I already said) there's too much room for variation in the flight characteristics in the Evo that comes from setup alone.
I recall a substantial difference (in my real Evo) between the stock paddles (with weights in) versus the stock paddles with the weights removed. There was even a larger difference when I tried MA 3D paddles on my Sceadu. (And I'll keep them until I wreck the flybar... then I'll try out these VPaddles that I've been waiting to fly).
Same goes for Main Rotor blades; they do make a difference in how it flies.
As a result, you can't expect the sim to fly exactly like your real Sceadu. (Well, at least not before you've tweaked the sim to match the behavior of your
specific setup.... and the only way you can tweak it to such accuracy is if you've flown your real bird enough...)
So my advice would be to just sim helis, period. No matter how closely one person's idea of a 'perfect match' in a sim would be, your view will differ.
Kinda like how your opinion of another person won't agree completely with mine. The difference may be quite stark...
The last thing I want in a heli is a few loose screws.
