It would be a long list, if I listed them explicitly, I find that the quest is not so much, what services are done better by someone else, but rather what service best meets my usecase.
For instance I use none of the app apps other then camera, but that does not mean that I would recommend my setup to my father, generally I would advocate for the stock app/services and when a specific need arises to then switch.
Painting in broad strokes though, I use google apps or a selection of third party apps to give me cross device consistency on the app side, and none of apples servies because I find them to generally be lacking in some sort of critical feature for my usecase.
