It’s not capable of creating precise or maintainable documents (e.g. no styles as others have mentioned), which is a very common need that it’s adjacent enough to that lots of people use it for and then it fails.
That is, I should be able to define a "Code block" style that should appear in the same dropdown where google docs lets you select heading levels. When I select that "Code block" style, the app should format the selected bit of text according to the syte's definition. For instance: use a monospace typeface, apply some margins to this paragraph and paint a gray background on it.
Likewise, I should be able to update the style definition and all code blocks should update accordingly.
This is very basic functionality that has existed in word processors since... forever. Large and/or more complex documents are simply much much more painful to maintain/evolve without this feature.
But working on large files is ridiculously painful. It's just not as as good as a native app. I don't want to give up my ability to work on large files in a performant fashion, which I do all the time, in exchange for collaboration support I do occasionally but a worse overall experience and frustrating lag compared to a native application.
I wasn't aware that Google has a different one. I have never used more than simple sums and differences in Google sheets. Can you give an example where Google offers better, incompatible functionality?
