Tough decision. I am partial to the Bianchi, because I had a low-end 1962 model and, as a teenager, lusted after the Specialissimas. I also like the Frejus because it is equipped like a Capo Sieger or Modell Campagnolo, with GS derailleurs and aluminum crainrings on cottered steel cranks with integral spiders.
I am a bit overwhelmed with four bikes of that vintage, three of which are currently bare-frame projects, but it was a delightful era, with lots of beautifully made frames with generous tire clearances.
