I can't feel the difference as a recreational skier. I've only come to a sudden stop that I couldn't stay standing once, and that was going from ice to asphalt.
Oh man, that's base grinding 101 right there for you. Ow.
Anyway, I have a friend of mine who uses "Stunt Wax" which is advertised as "please do not scrape." He is not concerned with speed, and it works fine for him. He spends about 70% of his time instructing (he's PSIA), and I would assume that not scraping helps the wax just last longer whilst skiing backwards with kids.
Now that being said...when he is not scraping, and we are on the flats, I always always always outglide him regardless of how many runs each of us have done. I use Swix, and I scrape. Of course there are differences in weight and ski length that could factor in as well.
One thing that I see that keeps coming up that everybody seems to agree on...if the snow is wet/slushy, scrape. If you don't do that your skis will let you know they are displeased.
