They (Google Apps, and Office) are different. People who cannot take the time to adapt to different will always find the 'other' system inferior to the one they know.
On the exposure to a new system, the combination of using the previous system as the default exemplar, and using the trained work flow that the previous system encouraged, results in the second system being rated 'inferior' to the extent that it does not exactly duplicate specific characteristics or support exactly similar workflow.
It would be equally wrong and cynical for me to discount opinions for imagined reasons like, people who fit a younger or tech-friendly profile latch on to new technologies for the sake of being cutting edge, or that people in an industry that benefits from adoption of web apps would be biased towards Google apps. (Though the temptation exists.)
To the extent that I could understand it, the OP argument was that it was worse because it was different. And it is that claim I disagree strongly with.
