When I paint, I always use Sherwin Williams or Duron. For rollers, it's always lamb skin rollers for two reasons, 1) it paints better and does not leave roller marks 2) there is less splatter from the rollers. But splatter is not a problem because I will always cover any and all furniture, carpets, floors, etc.
Whenever I have a power washing assignment, I always use house and siding cleaner; Krud Kutter is the only brand that I use for siding cleaners; it is an eco-friendly, non-toxic solution and yet tough on stains. For deck power washing, I always use a deck cleaner. With a 3000 psi power washer and quality cleaning solutions, all jobs comes out looking brand new!
