Word suffers from the case that it needs all features for all users accessible at almost all times (despite most people only needing about 20% of it at a given time). Word actually has a great "Focus Mode" if you can find it (among other ways to get to it there's a button for it in the status bar these days).
I wrote most of a novella in the iOS version of Word last year for NaNoWriMo, mostly because I really liked Word's OneDrive-based sync to make sure I was always up to date no matter which device I used and that I could reasonably trust offline sync in the rare cases where I worked on the document on multiple devices "in parallel" because one was offline. The iOS version defaults to "Focus Mode" and that eventually pushed me to figuring out how to get the right "Focus Mode" settings on my desktop to get a similar writing experience, which turned out to be easy when you knew what you were looking for.
I think it's all another reminder that it isn't necessarily your tools, but how you use them and how familiar you are with them. In a nutshell that is most of the discussions here, use what you like and if a 30+ year old word processing tool meets your needs, wonderful. On the flipside, the modern tools aren't without their merits and there are similar familiarity tricks to using them that maybe just take a bit a seeking them out or learning them.
