idk how you'd judge success in this case but humans are likely the only 'virus' that has spread to such diverse environments & have a 'lifetime' OOM more than other viruses.
Plenty of animals, bacteria and plants that outclass humans in everything but one single thing: Going to the moon/space /running. But Tardigrade can live in space, so there is that:P
the quote called life a virus, not just humans. but while on the subject you could say humans cant compete with literally all life but against any single species we'd be most
