It works pretty well, but I wouldnt call it a night & day difference.
I helped my dad put a new floor in the game room of their house, which is above the garage. When the old floor came out we found that there was NO insulation whatsoever. We had always wondered why the hell it was so loud when the garage was opening or closing, but we attributed it to the depth of the floor. Anyway, we had a guy come out and fill the entire floor with spray insulation and now not only is the room quiet, but the temperature is perfect. The massive window on one end used to heat up the room like a furnace. Between the new solar screens and the insulation it's a completely different room now.
I'd insulate the shit out of the attic. New cookie-cutter houses are so shitty these days it's unbelievable. $200,000 ten years ago and they didn't even put insulation in the fucking floors.
Plus, when we tore out the staircase to fix some squeaky steps we found a 3-foot tall pile of garbage and fast food refuse they had stashed away. They actually filled the goddamn space under the stairs with FOOD GARBAGE. We couldn't believe it. We even took pictures. Wendy's, McDonalds, even a Pizza Hut box. Absurd. Rats and mice, anyone? Keep in mind this is a 4,000 square foot, 2-story "luxury custom home". What a joke.
