Microsoft Office

Word processing software
LibreOffice

My recommendation is Only Office.

Though I really wish there was a better webapp version similar to Google Docs. Only Office can run off the web but it uses a bitmap render thing which slows down it's performance a great deal.

Office is specifically native versus webapp, but all major open source office editing webapps also have native versions (libre office for Collabora, and OnlyOffice for OnlyOffice Server)
