Hi. Upgrading to Office 2021 Professional Plus may be a worthwhile decision, but it ultimately depends on your specific needs and usage patterns. Office 2021 Professional Plus: offers a one-time purchase: you pay a one-time fee for the software and are a permanent owner. It includes Word, Excel, PowerPoint, Outlook, Publisher, Access, and OneNote. For your basic needs, Office 365 Personal may be sufficient. However, if you favor offline access, a one-time purchase, and a full suite of applications, Office 2021 professional plus may be a better fit. Hope this helps!
