This is my opinion
Search: Push
Google = Bing! (seriously)
Calendar online: Google by a landslide but if you include Outlook 2013: Slight edge to Outlook.com
Google Calendar > Outlook Calendar (nobody makes a better online calendar than google)
Email: Outlook by a landslide
Gmail < Outlook.com: even if you use gmail, I recommend you import your email to outlook, the tools are much superior.
Cloud Storage: Onedrive by a landslide
GDrive <<<< Onedrive: If you subscribe to office 365, you get a lot of memory. I like how it integrates both into the finder on the MAC, and the file explorer on Windows 8. Also one drive integrates with office apps across all platforms.
Contacts Google wins this one.
gmail > Outlook.com: Google contacts I find that is syncs better across platforms while outlook might be missing information that is available on outlook.com but doesn't sync with your android or iOS device.
gmail package < Outlook Package: you can use outlook to import all your email addresses, send email from that address as an alias, import gmail contacts into your people hub.
Office: Not even close. If you own a chrome book I would suggest office online verses the crappy Google Docs.
Google Docs < MS Office: it isn't even close. MS office is a standard. I would take office 2003 over google docs.
email programs-
nothing beats outlook 2013 for productivity, best calendar, contacts and email, and yes you can sync your outlook.com account to it.
You will most likely get more support from Microsoft than Google. Google is known for discontinuing products at a moments notice while Microsoft isn't. Also: google has no support for windows 8, while Microsoft provides support across every ecosystem. (BB, Android, iOS, OSX, WIN8, Windows Phone)
The another big issue is going to be privacy, Google is an advertising company first, while Microsoft is a software company, they both provide similar services but both make there money differently (google: ads, MS: Software & Services). Google sells your information and uses it to display ads.
