Where WordPress is the better choice
WordPress is the better fit for a single small venue with a light event calendar and no complex ticketing.
It is also the right call for an organization that already employs a WordPress developer, where budget is the binding constraint, or where the site is mostly marketing content with events as a secondary concern.
If a venue runs a handful of events a month through one ticketing provider and has in-house WordPress skills, the case for a specialist platform is much weaker.
