I don't know that any American maker did any better between 1960-72 or so. I can't think of a car that wasn't early-50s engineering all the way through, with bigger and bigger engines stuffed in as the years rolled by. I think the vaunted differences between Camaros and Mustangs and Cudas and GTOs are microscopic when you step back from the partisan BS of the era. Something quite accessible like an XKE would run rings around any production US car of the era except in straight-line performance.

The exception is the Vette, but it's always stood alone and even those have iffy handling and braking by modern standards, especially with the monster rat motors.
