Holding a steel one in my hand it looks well proportioned. Since they are steel I see little need for rethreading.
I also have an alloy one. The arm is proportioned like a Record. Notably it is missing the sharp edge at the spider/arm junction.
I guess one value is the flexibility of the venerable 86mm BCD. That allows use of TA rings to make triples etc. with a minimum of 36T.
Campy seemed bent on not exploiting this flexibility by only offering 42/52 ring combinations as far as I know.
