True, they are less busy, but it does not mean GPS is not used for instrument approaches (as parent implied).

I fly airplane without IFR GPS (IFR student), but ATC is trying to assign us GPS approach all the time (when coming into airport with ILS). As far as I understand, GPS approaches are used, even if they are less critical in busier airports. Besides, sometimes ILS is not available in bigger airports as well.

ILS was not available on the SFO runway the Asiana aircraft crashed on ~2 weeks back:

Yes, but the weather was clear. No need for ILS in such weather.

Unless of course you've never landed at SFO before in an aircraft you're barely type-rated on.

Neither should matter. A visual landing at any airport is pretty much the same, and the basics don't change for different aircraft. There's nothing at all tricky about a visual approach into SFO.
