I *strongly* disagree.  What vintage chips are you speaking of?  Yes,
there were some bad chips at the beginning, but that has been remedied
*long* ago.  I'll even let you have the early Enhanced ones (which I
just don't know about, because I didn't pay any attention to them when
they were first released).  How much better did Intel's early Enhanced
(by this you're referring to write-back cache, correct?)  chips work?

When you say "non-enhanced" ones generally sucked, do you mean all the
chips before the DX4s?  If so, you're just plain in outer space.

I have had a 5-volt 486DX2 80MHz (one of the first ones made -- bought
it right when they were released).  It is a very solidly made chip.
It has been pushed very hard at times, and has never flinched.  It's
as reliable as any computer I have used.  I have experience with
*many* other people running similar AMD CPUs.  To say they "generally
suck" is to be totally misinformed.

To say they aren't always plug compatible, though there is a massive
weight of evidence against it, I could be convinced to believe in
certain odd situations.

Yes.  Really nice.  Just like my AMD 486DX2/80 when I first bought
it. :-)
