Owners mistakenly ASSUME all PMCs offer the exact SAME SERVICES and PERFORM those services EXACTLY THE SAME WAY, so price is the only differentiator – so, they often select the first PMC they call or that calls them back!

But the items that are specific to financial performance and the safety of yourself and the neighbors, etc should be the ones you pay more attention to.
