It's not about what I (as a web dev) need, but what works for "halp, I need a website" clients who don't know anything about tech. Hugo still implies the need for a build setup and hosting, which in turn means DNS, SSL, CLI, etc. Which often means more dev time. Your average yoga teacher or restaurant or nonprofit would have no idea how to deal with all that (and they shouldn't have to). That's why the page builders are better for them, IMO.
