Unless you are dealing with special features, please use Google Slides.
Microsoft tools are still in the Enterprise, despite Google tools. Indeed, they are used for different purposes.
For instance, Microsoft Powerpoint (any version) is used for Marketing and Sales presentations.
All Ceva countries can use Microsoft Powerpoint, (however Ceva pushes people to use the same file format - pptx - for all Office documents in order to facilitate productivity) .
