I went cold-turkey on MS Office in 2016
and don't regret it. In 2015, I decided that I would not pay any MS tithe once I retired.
Now it is Linux all the way.
I use a 2015 vintage 15in MacBook pro (bought secondhand). It used to run CentOS but now run Alma Linux.
Libre Office does everything I need.
Since 2016, I've written well over 1.5 Million words in Writer and submitted over 100 stories to Amazon Kindle with no issues.
I accept that for some (as in very few) power users LO is not up to the job but for 99% of the rest of us it is fine.
YMMV naturally.
