In what way? Venera_7 was the first successful landing on another planet, by anyone. The Mars_2 lander was the first man-made object to reach the surface of Mars, though it crashed. Mars_3 managed the first soft landing on Mars and sent the first picture from the surface, although contact was lost soon after. Still, that's 5 years before the first successful American landing.

But look at their failure rate. With spacecraft you have to take the time to do it right.
I would not have thought a link on space probes could be so controversial.
