Didn't work where I worked/lived/experienced. There is no incompetent nice. They are usually "nice" but they end up wasting significant time as they try to "show off their work". There is also no competent jerk. There is bad management. Not everyone wants to train juniors or deal with them on a daily basis. There is also a set of people who wouldn't mind telling snarky comments to each other; and another set of people sensitive to any gesture you make. Put every set separate from the other. tl;dr; There is only competent nice and incompetent jerk. Otherwise, it's a management failure.
