The truth is it didn't.
No support (or equivalent in this case) for VBA macros (Swift should come rescue us), no pivot tables (!!!), a lack of versatility regarding the styles, a lack of user-friendly mathematical formulas built-in in Pages (it's already in Apple's Grapher, why not in Pages ?), the absence of many important mathematical functions in Numbers, the absence of many graph types, the lack of compatibility with other apps, the lack of collaborative work, a lack of synthax analysis (at least in French), ... too many elements where Word and Excel... well, excel over Pages and Numbers.
If you need any or all of these relatively obscure features, sure. The workflow I was able to establish with Pages is second to none in my experience. Sadly Apple decided to delete many of the features of Pages that beat Word cold. They seem unlikely to return.
Compatibility has never been a problem for me.
