To give you my tongue in cheek answer: I think the answer depends on whether or not you ride a helmet, or ride Campy or Shimano.

I have both, but probably don't ride enough to notice much difference - since the alu bike has skinnier wheels and higher tyre pressures than the steel ones, I suspect I wouldn't pick up on the difference in the frame alone...
