If unissued, I would prefer the Argie, but only b/c I already have an unissued 1908 Brazillian that's almost identical to the 1935. The 35 is a nice gun, no doubt, with a cool logo, but the unissued Argentines are a sight to behold, complete with white receiver and pre-war (ww1) fit and finish, flame blued parts, strawed springs, etc.
Honestly though, I wouldn't buy either as a "shooter". Lots of issued guns around for that.
