George, they both are laborious. I prefer blasting, as I think the quality of finish removal is more thorough, and faster.
I just sanded a house down in December, and I don't know if I'll ever do it again, lol. Sanding for me ended up being harder on my body than blasting.
That being said, blasting takes practice, and sanding, not so much.
Sanding, expect 10-20 square feet an hour, and as little as 2 square feet per sheet if the stain is tough, gooey, etc.
Blasting, anywhere from 80-200 square feet an hour without prep. Material usage varies. Some people sand after blasting, but at least they are sanding wood, not stain. Big difference in the two.
Does this help at all?

I have a restoration company and we use crushed walnut shells to blast log buildings and use a good quality stain to seal the building when completed. An average 1500 sq ft log building takes about 3-4 days to blast and stain. Blasting leaves the logs a bit rough but ideal for absorbing a good coating of stain. Generally you can count on using only about 1 gal stain for every 120 sq ft of blasted surface. When we leave the site, the home is like new again. Please don't blast your logs with high pressure water as it tears them apart.
