I think Monster was good for a while. Never used CareerBuilder. I've used Indeed and Linkedin with decent results.
Monster was fine for about the first 10 years of it's life. After that they started to buy companies to try and keep relevance, and the indians started to flood in.
They still had "Screen Name" in profiles up until about 2015 or so, maybe later - I thought they were competing with the Space Jam website to keep the oldest looking site on the internet alive.
