These are my top Android Apps - What's the counterpart for WP7/8?

As I'm a gadget-junkie, I'm always looking to try the latest devices from a variety of OSes and manufacturers. I'm familiar with all of the OSes (BB, iOS, Android, WP), but I'm not quite sure on where WP currently stands since I last used my Radar 4G before giving it to my dad (his first modern smartphone). Anyways, these are my most used apps on my Galaxy Nexus running Android 4.1 Jellybean - what's out there TODAY in the WP world?

  1. Facebook - obviously, I know that WP has FB integration...but it seems to ignore some filters/settings I had set up. For example, there are some people who I made "Acquaintances" or to show only important updates, but Facebook seemed to ignore that in the People Hub and would show me their statuses anyways. Also, I upload a lot of photos to specific albums and of course use most of other things that Facebook has to offer.
  2. Foursquare - is there an official app yet? I prefer having first-party apps for social networks (the less 3rd parties who have some sort of access to my data, the better).
  3. Google Voice - I use Google Voice as my primary mobile number, for calls and texts. How good is the integration? Is it PERFECT like it is on Android?
  4. Google Talk - my main method of communication outside of SMS.
  5. Google Reader
  6. Gmail
  7. Google Calendar - I use multiple calendars
  8. Google Maps - how well does Bing maps compare?
  9. Yelp
  10. Pocket/Read it Later app
  11. Reddit Apps?
  12. Astrid - To Do List w/recurring events and reminders
  13. Uber - for taxis in Chicago
So, thoughts on how easy/painful the switch would be?
