However, some users face UI/UX challenges and document formatting issues, especially with complex elements.

    LibreOffice does basically everything you can do in Microsoft, and it's open source and doesn't constantly try to call home.

    Plus, LibreOffice is free.

    Doesn't mess up formatting like LibreOffice does.
