People are getting confused about what a scrub plane is.

  A regular smoother or jack can't take a very big radius. The width of 
the blade/chipbreaker only lets you use so much
These are just coarse set planes.
  A coarse set jack is more used in my shop than a true scrub by far. I 
use them constantly.

Scrubs are very narrow with no chipbreaker so you can grind a deeper 
radius. They hog chips faster than anything but they are not the easiest 
planes to control.
