I've never seen a single person ever use Number or Pages in my 20 years of Mac Support.
I can think of only two reasons why that is true:
1. Those you support who use Pages and Numbers don't need your help! Perhaps, that's because they find them easy to use or, perhaps, it's because they know what you think of them! ?
2. Alternatively, you work for a company that has standardized on Microsoft Office, so no one uses Pages and Numbers and there is no need to support anyone! ?
Oops! A third reason.
3. You need to get out more! ? (“never seen a single person ever use…”)
I'm a Word-Excel user, but appreciate the power and ease of use, even elegance, of Pages and Numbers — and would never sweepingly dismiss them!
Now, as to Pages…
I really hate how to Pages app is constructed with the tools on the right side
I love Word, and still use 2011. But, from 2016 and on, and, especially, with its most recent versions, all those ribbons and toolbars are oversized (although one is tiny and hard to even read) and they take up so much space in the top half of the screen that it cuts into the viewing area of documents. Sure, you can hide them, but then you lose 1-click access to key commands. Libre Office provides Word's classic GUI.
But as to Pages… it has a real advantage in parking the tools on the right. it gets them out of the way, so you can really see the document and see more lines of text — far more than in Word.
Plus, after 2011, Word's 2016+ versions also lost all manner of customization — and, for many people's uses, including mine, were a major step backwards that disrupted long-established work flows.
I don't know if Word ever fixed its handling of section breaks and headers, but Pages does that much easier, much simpler. It's also able, like Libre Office, to open documents created in old versions of Word that Word 2011 and later simply can't open.
But command-click to select a sentence is much simpler than LO's triple click and it and Redo the last action are among many key features that Word has that Pages does not.
Bottom line: So much depends upon needs, habit, familiarity, and comfort, that heralding any of these as ”best” or “clearly superior” to the others disregards what people use them for and how they use them.
