Compared to what? I think it won over its direct competitors of Salt / Puppet / Chef, though there's more than that now. It's not ubiquitous, but it's pretty common, and useful, even if the syntax is truly inscrutable.

I feel like it's pretty well used for persistent installations that just need regular config updates, and we have better tools for VMs that get spun up independently for every reconfiguration.
