We've all heard about the horror stories that it doesn't matter what you do with Google you cannot get human support unless you get to the top of HN or Reddit.
MS are totally different, they offer support for every service, you just have to pay for it. I think they also offer different levels of support, some of our programmers at a previous (small) company could talk to the Silverlight team over problems they were having after it just came out.
Funnily enough, when I google "google paid support" the top result is this little (frightening) gem:
http://support.google.com/accounts/bin/answer.py?hl=en&a...
Compare that to this, "microsoft paid support":
http://support.microsoft.com/gp/services/en-id
I'm in no way affiliated with MS, actually use Google Apps myself.

I just went their with my free apps account and it's not exactly forthcoming about how either.
MS engineers complain about all the bureaucracy involved in change anything - check with legal, update user docs, update support docs, update the tests, check the internationalization and accessibility. But that's the cost of providing a solid product.
Google has two big products - ads and search. Search is more or less a single text box, and a list of results. There's some bells and whistles, but as long as you can type in a search box it's good enough. Ads are similarly bullet proof (though plenty of people get pissed off at being blacklisted).
I worked for a Gold partner at the time. Now I work for a company that buys hundreds of thousands of dollars of Microsoft software, and while I'm not in contact with support, I hear they've also done well by us. They even do special patches if needed.
OTOH one of the biggest retail companies here tried a companywide rollout of Google Apps for businesses and discarded it mainly because of the lack of support.
Most recently, I filed a support ticket online and my phone rang a few minutes later. On the other end was an MS support rep who stayed on the phone with me for 40 minutes, including a screen share, until my issue was resolved. At the end of the call he left me with his direct # and email, and said that I could contact him directly with any future inquiries.
Really can't ask for much more than that.
