Office Professional 2016 is $400. The closest equivalent is Office 365 ProPlus (the other enterprise plans add lots of extra stuff not included in the standalone) which is $12/mo. For an upgrade cycle shorter than 3 years, 365 is cheaper. Even for a longer cycle, the standalone is a significant outlay compared to the monthly cost. So you are comparing a no-risk (since you can always fall back to the native apps) negligible cost solution to the google solution
