One of the best products. What I really love about SharePoint especially is SharePoint online.
Not only will you get the SharePoint benefits, but it's also highly available. I made a migration with more than 4 companies at Egypt from file server to Sharepoint online. They were very happy because of the stability of the cloud and they forgot the troubleshooting to the servers. They can just focus on the administration of SharePoint online.
Also one of these companies doesn't have an IT professional admin or even help desk, so they are working with Skype for Business online. With Exchange SharePoint and one drive, they are happy because of the storage they have as well as not needing an IT professional to administer it. It just requires adding some features and assigning some permissions and they are very happy and satisfied with SharePoint (the Office 365 suite).
Disclosure: I am a real user, and this review is based on my own experience and opinions.
