either statement is useless without knowing your inside leg, the effective top tube and stem length. manufacturers sizing can be center to top or center to center, this and the differences in compact and traditional geometry mean that effective TT is the main measurement that's going to tell you if the bike is likely to fit you. but unless you have been fitted properly to find out your ideal TT length it's all meaningless.
there are lots of people riding bikes of the wrong size, statements like 'A friend is 5 11 and a 58 fits him perfectly' isn't going to help determine the right size bike.
i'm 6ft1 and a 55 fits me perfectly.
