I think it is safe to say that our discussion is based mainly on personal experience, which explains the difference in our opinions. From what I can understand, your experiences are from using Nexus devices, while devices I have used are mainly HTC and Samsung. I have used every single version of Android since 2.1 to the latest 4.2.2 (on my Sensation, abeit through CM10.1), and to me 4.2 is the version that has the biggest problem with Bluetooth performance, among other things. And frankly, if you follow tech blogs like Engadget, The Verge, etc..., you ought to realize that there are quite a lot of articles talking about bugs that 4.2 introduces (probably as much as iOS 6). Seriously, ICS and 4.1 did not manage to attract that kind of attention.
Again, I wholeheartedly disagree... The N7 is the only Nexus device I've owned. Previously, I used no-name tablets, Asus tablets (original TF101, which came with Honeycomb, which was bug-ridden), and an HTC phone (which runs ICS and is also bug-ridden). All have had far more bugs and instability than 4.2.2 in my experience.
You are basing you entire opinion based on what you read on the net, at least for 4.2.2 (I keep thinking of that damn State Farm ad - you know the one - "he's a French model"!). I'm basing my opinion on actual usage (of both previous versions and 4.2). You really can't go by your experience with CM10 - it is no longer Android 4.2.2 and introduces it's own bugs and issues.
Anyway, we'll have to agree to disagree on this one!
Anyone else care to give their experiences of previous versions vs. 4.2(.2) in terms of stability? Maybe it's just me....
EDIT - By the way, I don't experience any of the issues reported in that link. Well, actually, the N7 auto-brightness has never worked very well on the N7, but I think that is a hardware-design flaw, not an Android issue (since the problem is not 4.2 specific).
