I've not found any problems with 5.0.2 since getting it last week, bar the launcher (Google Now in my case) still restarting quite frequently which is a bit of an annoyance.
I do think launchers should never be shut down to free up space, no matter what. It's a perception thing, and obviously gives masses of ammunition to the fanboys.
Some Moto G (single SIM) versions got Lollipop very quickly, in keeping with Motorola's recent track record on updates, but the issues that forced out 5.0.1 and now 5.0.2 did trigger this delay, so hopefully Motorola only signed it off once almost all issues were fixed.
This is why Android 5.0.x has been slow to appear on other handsets too, despite most companies promising quicker updates (knowing that not doing so will put people off, as HTC discovered a while back when an awful lot of long-term loyal users got really annoyed).
