Office 365 is the best option for anyone who needs access to the full range of apps and perks on multiple devices. Also, you can share an account with up to six people. It’s also the only option that offers continuity of updates and upgrades with a low cost of ownership. However, there are monthly or yearly costs, and over time, you may end up paying for features that you’ll never use ($70 annual cost)

If you only need the basic features on a single PC, Office 2019 is probably all you need, as it allows you to access the must-have apps, such as Word, Excel, PowerPoint, and Outlook, with all the necessary functionalities. However, paying upfront can be pricey, you have to pay again for upgrades, and you don’t get extra perks ($150 one-time cost)
