OP: More importantly, have you tried Microsoft service yet? How'd it go?
Not sure how things will be now, but of course at launch MSFT didn't want any bad press. When I reported my clicking disc drive (that would read perhaps 50-60% discs) they were very helpful. Expedited me a coffin and when the PSU started to have issues they offered me a free game (how I got my copy of Forza 5). The only downside was first time it was 2-3 weeks for the disc drive (due to holidays) and second time they just sent me a PSU didn't even ask for the original back.
Sony on the other hand, I had to talk through 2 possible 3 reps before they even offered to do a swap, and I wasn't told if I was getting a new or refurb unit (due to shortage, MSFT said I'd get a new unit and I did). Eventually after the hassle my GF (who bought me the PS4 through Amazon) got them to do a swap. I got my new PS4 from Amazon the next day even before the Sony shipped coffin arrived. And Amazon in their awesomeness did a re-order (so I got a second 1 yr Pass for PSN, and a controller). Since the pass was digital they said I could keep it, just send back the controller with the broken PS4. EDIT: Actually, reminds me because I never returned the broken PS4 directly to Sony about a month later I got a call from customer service asking why, I explained Amazon did a better job taking care of me and I got a $50 PSN code as an apology, so while Sony did suck, in a sense I got more out of that broken unit than I did the Xbox, but still see the TL;DR. Sony sucked.
TL;DR:
MSFT was awesome with their responses but it was close to launch not sure how they'll be now. Sony sucked.
