Venera 7 lasted less than an hour and only transmitted one or two crappy images, along with some sensor data. Granted, humans can't do any better on the surface of Venus due to the temperature and pressure, but humans can do far better than that on the Moon with ~1969 technology, and they did. Humans brought back many kilograms of rock samples, they set up a bunch of experiments, they drove around for hours on a buggy (in the later landings, not Apollo 11); they did FAR more than any lander of the time could possibly have done.
