The other difference is that if something goes wrong and you are put on a different flight in coach, they don't owe you anything. And some agents get confused about whether it is a paid first class ticket (it is) vs. a coach ticket with a free upgrade. It matters when determining the order of upgrades on your rerouted flight.
