Ive spoken with a lot of drivers and even a few hobby shop employees on this issue. As well have driven a few of these. Good thing , most everyone agrees on these comments.
Mazda 6 has probably the most turn in of any body. Therefore very good on technical / parking lot style tracks.
Nemesis , less turn in than mazda6, but almost same.
Stratus 3.1 is just plain good all around, stable.
And the Alpha is just plain old.....
