I like LibreOffice because 1) it is intuitive to use, you don't have to read a manual to use basic functions; 2) it is trouble-free to use without Internet in a sandbox (firejail); 3) it can be extended with add-ons; 4) it can read proprietary formats, unfortunately sometimes necessary; 4) its range of functions allows you to have no disadvantages when using free software for word/table/presentation editing.
