If you are still using Microsoft office 2007 as your productivity suite, then go and purchase any latest productivity suite. Because 10th October 2017 is the retiring date for Microsoft office 2007.
Microsoft said, “Office 2007, like almost all Microsoft products, has a support lifecycle during which we provide new features, bug fixes, security fixes, and so on. This lifecycle typically lasts for 10 years from the date of the product’s initial release, and the end of this lifecycle is known as the product’s End of Life”.
If you want to work fluently without interruptions, bugs and security issues to upgrade your productivity suite to Office 365 or Office 2016. Both Office 365 and Office 2016 comes with all the latest features and latest upgraded applications.
Office 2016 is not on subscription process, it is one time purchase application. No updates are included in Office 2016, you have to purchase again whenever new version comes. Office 2016 is sold as digital download and not in a disk on a shop.
Office 2016 comes in two versions, Office Home and Student 2016 or Office Home & Business 2016. Both of them have Word, Excel, PowerPoint and OneNote for one PC or Mac. Office Home & Business 2016 also includes Outlook.
Office 365 comes in annual subscription process. It includes regular updates every month and it is also comes in two versions, Office 365 Home and Office 365 Personal.
If you buy Office 365 Home then you can use it in up to 5 PCs or Macs. You can use all its advance features on your mobile phone whether it is android or IOS but have Office 365 subscription.
With Word, Excel, PowerPoint, OneNote, Outlook it also has Publisher and Access. Both the versions of Office 365 includes 1 TB of OneDrive storage and 60 Skype minutes.
If you compare between Office 365 and Office 2016, Office 365 is much better option if have regular work on productivity suite but if you rarely use it and don’t have much work on Office then go for one time purchase.
