Hm. To be honest, I don't have any stake in this discussion, despite my previous snarky comment. I have given up on 4e after years of trying to get into it - the only time I really enjoyed the game were either in situations where die rolls were not a factor (ie, "it could happen in any system" moments) or where I took something WotC developed and fixed it so it was fun again (I'm looking at you, Sceptre Tower of Spellgard!)
As for Pathfinder/3e, while it's going to be my new system, it needed quite a few tweaks before I'd get near it again.
I will share two stories, though.
First was when I got my Character Builder subscription. I had a computer problem that prevented me from accessing the Dragon and Dungeon magazines. I could get my Character Builder stuff, but had no access to the PDFs.
I called the available numbers, and got no reply. I sent off three different emails to EACH of the three different email addresses that might deal with such a problem. And got no reply. At all. For about two weeks, I could not access products I had paid to access, and got NO customer service replies. I almost cancelled my account, but wound up getting my tech-savvy brother to fix the problem with some computer voodoo.
When Paizo first started releasing Rise of the Runelords, I'd get the issues mailed directly to my door. I got them all, except for issue #3. Basically, it got lost at the post office. I emailed Paizo, and got a reply within two or three days that said "well, we sent it, and it went to the post office." the post office never said one way or another what had happened to it, but Paizo did send a second copy, which showed up at my door. Even though, for all they knew, I was lying and trying for a second copy.
So, in terms of pure customer support, Paizo wins, hands down.
Funny story I just remembered: when I cancelled my sub to Pathfinder (I had switched to 4e and had basically stopped even reading the AP stuff that was coming in, so figured why not save some money), I found I kept getting issues delivered to me. I was not being charged for them... but the issues kept showing up. This happened something like four or five times before I felt guilty and sent them an email alerting them to what was going on. But yeah, that's how much Paizo wants to please their customer - they'll send you the stuff for free!
