What the classic Wix Editor is good at
The Wix Editor is the original builder: pick a template, drag elements around a fixed canvas, publish. It's genuinely fast for a straightforward site, a local business, a personal brand, a landing page, where the goal is getting something live quickly rather than building something highly custom.
It also comes with a large App Market and built-in apps (a blog, an events calendar, a store, a booking system) that work reasonably well out of the box for common use cases. If your business needs a standard blog or a standard booking calendar and nothing more unusual than that, the classic Editor's defaults can carry you a long way without any custom development at all.
Its limits show up once a site needs precise responsive control, a design system that stays consistent across dozens of pages, or a CMS structured around content that doesn't fit the built-in blog or store templates. The Editor's responsive behavior is largely automatic: desktop layout scales down to mobile, which is convenient until you need something to behave differently, not just smaller, between screen sizes: a different navigation pattern, a reordered layout, or elements that should disappear entirely on mobile rather than just shrink.
