Everything should be identical apart from the steel frame for a true comparison and in that case you would not notice the difference.

you would notice the difference between a whyte 19 and SC chameleon (i certainly did)
both alloy but very different in construction and the way they ride.
i test rode 2 identical steel mtb frames one 853 and one 520 (parts were swapped one to the other). there was a difference between the 2, not because one was made from expensive steel but because that steel enabled the top and down tubes to be smaller o/d. this will affect the stiffness of the frame. (FWIW the back end was the same on both)
