Bonobos still have alpha females and alpha males, and, according to the article, though they have less violent conflict than chimpanzees, they are still more hierarchical than human foragers. This is not a binary distinction, but the review article definitely supports the “less egalitarian—more egalitarian—less egalitarian” progression.
There are males with greater status, but the typical associations of “alpha male” don’t really cover it. They’re simply males with higher-status mothers, and their relative status only really holds leverage among the other males; they’re still subordinate to the dominant coalition of females.

(The basic progression I don’t take issue with.)
