in general .... it depends ....
rechroming previously chromed parts is more expensive [by far] than chroming previously painted parts, the chrome has to first be removed, which in itself can damage the shape of the part
some "new" [reproduction] chrome is low quality, no copper layer ... some chrome shops do poor quality work as well, regardless of price
some reproduction parts, chromed or not, are a poor fit
some parts just aren't reproduced
generally, check yer wallet and income, decide what you want the vehicle for
