Dip-scalding takes a bit of setup, but once things are ready to go (water is right temperature, pig is hung) then its 4-6 minutes of dunking and, with 2-3 people with bell scrapers in hand, about 6 minutes of scraping and you're done. Really, that fast.
I did this as a novice in a workshop with other novices. The only parts that took a bit longer were the armpits (those hairs needed shaving, not scraping) and the head (as the face was quite wrinkly). I did this on kunekunes, which are similar to pot bellies, ie: not the biggest pigs around. I'm told a more typical big pig takes about 8 mins under experienced hands.
If you've scalded at the right temperature for the right length of time, then the hairs come out quite readily under a scraper.
You have about a 10-12 minute window for doing your scraping as the pig cools down (less, if out on a chilly fall day), after which point the cellulose of the skin starts to tighten up again and hold the hairs - it's much harder to scrape after the scald wears off, go to shaving at that point.
I'm also told that it doesn't work to give the pig a second dipping, the skin starts to get gummy and things go bad pretty quickly.
Why scrape instead of just skinning? It doesn't take that much longer to do and the amount of delicious edible material that is lost in the skinning is significant. As well, removing the skin makes for way more surface area for bacteria to colonize.
I have not tried pour-scalding so I have no comparison to make on that.
