Well I'm of the opinion that there is more than one way to First Class.
That doesn't mean that some First Classes are better than others, of which that can vary between person to person (and dare I say it, not even comparable on a single dimension!)
I suppose we're at a point as to whether a First Class experience is actually First Class (or deserves to be called First Class).
As it stands in a free market, if it's called First Class and it sells, well then that's probably First Class then...
