In my field, most of my clients want me to have the latest MS Office updates (I think it’s even in one of my contracts), and OneDrive has saved my ass on a couple of occasions when I’ve had computer issues. For those reasons, we pay for Office 365 (and install and use it on all our other compatible computers and devices; I think one of our relatives also uses one of the installs).
If I didn’t need it for work, I would just buy the one-time license and use that until updates stopped.
