Is Word the best option for writing and editing a book?

I have mostly used Word when it comes to writing and editing. I find it easier, especially because it helps always being able to see the word count, the pages, the grammar and mistakes, as well as it is easy to add comments. But I haven't tried a lot of other platforms/apps so I'm not sure if Word is the best option. Besides that and Google Docs, what other options are there? Any recommendations?…
