Word Document - Blog Posts

Fanfic Writers, this question is for you. What word document program are we using nowadays? I ask this because I still use Microsoft Word. In my personal opinion it is not as good as it used to be. I would like to try something different. I have tried Google Drive but I did not care for it. I would love to hear about other possibilities. I would like something that I do not have to save my work to OneDrive or anything like that. I prefer to save my work on a flash drive/ thumb drive. I am rather old school lol.
