This Is an Student and Home Subscription To MS-Office 2019 and Not an Office 365 Subscription. The difference between This And 365 plan is that 365 Offers all Applications Including Publisher and Access, While This Plan is For Basic Use and thus consists of Only Word, Excel, PowerPoint and Outlook. So Consider your Need (For Eg. I am a Student And my basic use requires me to only buy Basic apps like Word, Excel and PowerPoint) However you need Access and Publisher Along with OneDrive Storage, MS-Office 365 Suits you best. Also Note That 365 is yearly plan and expires after an year while this is lifetime plan.
