No, very different. The F430 Scuderia lacks grip. In every other aspect, it's almost a race car (that makes it different from every other "road car" in FC).
So, you have power,you have lightness and twitchyness, the car isn't "sluggish" at all, and it's well-balanced (not with a ridiculous amount of understeer or the odd downshifting of the 550 and 575), but ... it lacks
grip. So when you get used to the understeer that it provokes, and you are able to anticipate it ... you start to enjoy the oversteer
Last night I didn't have anyone to play FC online ...
(I saw a lobby with the F430 Challenge and assists on, and another with the 360 GT hosted by manunza - assists on also - but when I got there I saw a particular cheater I decided to avoid entirely from now on, so I left immediatly)
... so I checked in offline mode what was the first Trophy I had to complete. It was the 355 Berlinetta. I did it and I found it to be probably the closest car (but much slower and less prone to sustain "bearable" oversteering) to what I felt with the F430 Scuderia.
JvM was telling me the other night that the Scuderia gets better laptimes in the leaderboards than the Enzo, and that such a result is true to testes made in real tracks (notably Fiorano), because the Enzo is more powerful but the Scuderia is more of a racer (even if it keeps being a road car).
Oh, btw, I did a few laps with the Enzo last night and it was also a pleasant surprise, considering my previous experience with that same car in another game
Very difficult to drive, but fun.
PS - It's funny that the Scuderia was the car that interested me less in this pack (another F430 ... yawn). Sometimes, I get surprised
