This post is old, but I like Mr. Cutout too, Of course they are more for rendering and not models.
OK for street scenes but, REALLY hard though to find bland people just standing, maybe talking, when you need only one or two in a residential rendering for scale. (if you pay you get better poses it seems). So many are distracting, inappropriately dressed, doing distracting actions or poses. One thing I like is all the search filters for lighting etc. Quality is great IMO.
