We use Ektron as the CMS for our health system's website. Almost all of the production work is done in the communications department, though the site represents the whole organization. It would of course be next to impossible to run a website of this size and complexity without a reliable CMS in place, and Ektron fits the bill.
I wasn't involved in the choice. I like WordPress but my impression is it's not scalable enough. Hand-coding would be a nightmare. I've worked at places that have developed their own in-house CMSs, but those were tech companies. I would certainly not advise to switching to any of the above if I were in a position to decide. I suppose I could investigate WordPress, but as I said, it's my impression it's not designed for such a large, complex site.
It's well suited for the purposes for which we use it: running a large enterprise web site. It is probably overkill for something small. If you're a small business with only a few web pages, you are almost certainly better off using WordPress, I think, if only for the simplicity and (free) cost.
