Most airplanes land smoother with a little power kept in to be reduced by roundout. My old twin can simply not be landed fully stalled smoothly - you have to keep a little power in for greasers. That said, a fully stalled landing has benefits as it's easier on the brakes, uses less rwy etc. Do whatever he says, but if you want to impress your first female/male date, keep a trickle of power in.
