Fascists were too Totalitarian for my taste.
But, Hitler & even Mussolini beat FDR in economic growth during the era.
FDR a nearly Fascist guy himself achieved the fastest economic growth of any USA president in at least 100 years.
While FDR wasn't Fascist in the proper sense as he didn't have Councils micromanage the corporations.
Instead he micromanaged through regulations of the war time economy.
He also used Public works like a Fascist.
I'm going with the 'Nationalist for Social Democracy'.
