Classic for me, but that is not really a shock to anybody that knows me.
There's more to the answer though.
Todays lifter, generally works a split with a heavy emphasis on isolation movements as compared to the classic lifter. The classic lifter used a generally smaller number of moves utilizing a fullbody program most of the time. So, the overall flow of the body is a bit different for a classic as compared to a modern.
Even if the modern put on some weight in bodyfat, there would be some subtle differences that most people probably wouldnt notice.
