There's also specifically the difference that humans being onboard added much more tolerance when it comes to things like landing. Neil Armstrong was able to fly the lander to get to a safer landing area and was able to sanity check the sensor readings in realtime. In comparison, these landers have to do everything autonomously, the computer has to figure out where it's safe to touch down, it has to be able to figure out if a sensor is malfunctioning and if so, which is the one that's wrong. Similarly, previous uncrewed landers were not expected to be that smart, they just aimed for a patch of land believed to be flat and hoped for the best.
