Excel Unfortunately. Plus Outlook for work email and work calendar. Plus Teams for work collaboration. None of them my choice. I do use Keynote for all PowerPoints and then export. Perhaps I should get into the habit of using Pages, which imo has a nicer UI/UX and handles long documents so good. Although some tools I use, like Ulysses for writing, and Zotero for references, don't play nice with Pages compared to Word, and sometimes we have to do the clunky slog of collaborating on Word docs on Teams. Otherwise, I agree. For personal use, would rather be on Numbers and Pages.
