Google Apps v Microsoft 365, does it a benefit the team?

You now have a number of companies offering cloud computing services.  The services offered by each company vary although they are all services generally used in the business environment to make the productivity of the company more efficient.  These companies make all of these services available from within their cloud on the internet.  The products they offer from their clouds can be delivered in different ways.

If your business relies heavily on colleague collaboration then being part of a team is necessary; this is further complicated when they do not work in the same location on a daily basis so you really need services that allow for collaboration in real time that mimics the office working environment.  These circumstances are what cloud computing is designed for.

A simple scenario
You want 3 colleagues to work on a business plan, named BP, today for delivery by 5pm; the plan is part finished and really just needs tweaking.  The problem is A is in the office using a colleagues PC, B is working from home on their own PC and C is away on business working from their laptop.  How would our main two contenders in cloud computing allow you to work.

First up Microsoft 365
To start with all 3 logon to the companies account within the cloud.  They are all online and can chat and send instant messages and agree to start work.  They open MSWord each on their own computer and then open the document stored in the 365 cloud.
