Google Maps - resource hungry, always doing something in the background, slow .. replaced them with much better, unfortunately local, alternative
Google Play - two examples: doesn't prevent phone from losing network so I have to play with the phone in order to download updates; listing my applications always takes about half a minute.. even if I did the same task 5 seconds ago
Google+ - basically unusable, unbearably slow, doing stuff in background all the time, crashed whole system few times
The truth is I don't have the most modern phone, but it isn't the slowest either (it's single core 900MHz w/ 512MB ram). It's running on the latest available android for that device (the device was sold less then a year ago, it's from 2010). Can't imagine how those apps run on older/slower phones.
Side note: Another multi-billion dollar company that can't seem to produce working android application is facebook. That is the single worst application that I have ever used (some were worse (google+), but I can't really talk about "usage" with them). It's getting slowly better, but it's still a crap. Twitter on the other hand is great.
Personally, I've found Google's Apps to work the best and look the best...on modern devices.
What do you use instead of Maps?
I don't use Google+ or Facebook. Thank god for disabling applications. (I'm referring to the ones that are locked to your phone and cannot be uninstalled).

As for G+/Talk, disable sync or sign out of Talk.
And is location service tied to application named "Maps"? If so, that might really be the case.. although I only have this problem after I use Maps, not when I use other apps that require location.
I totally understand your points, though. I use an older device with roughly the same specs, and when I was using stock 2.3 it wasn't very fast.
