I own three pubs, 2 rambunctious dogs, and a 114 year old house. Something always needs painting, and this is my go to.
Scuff-x usually covers in one or two coats and looks good even if I slack off on the wall prep (although I usually wipe things down with tsp before painting)
Most marks wipe off with damp rag, and I’ve used a sponge mop to keep up whole walls in stairwells and hallways.
Touch ups blend well.
