Hmm, interesting discussion! While there of course is a lot of subjectivity involved, I'd say that many people will agree that there is a middle ground which offers the best price-quality ratio.
The very cheap teas are not worth their money or the time involved at all, and the more expensive teas take a lot of money to buy and a lot of experience and time involved to appreciate. They have their place, but as others said, they are not for every day.
Interesting metaphors for the asa vs. fuka discussion. I for example found fukamushi teas often more difficult to appreciate, the bright and sweet aromas of asamushi were more appealing to begin with. So i though that fukamushi is in a way a tea for advanced drinkers
That is not to say that the one is of better quality than the other - just my impression. And if we are throwing around metaphors, for me a good asamushi is like listening to Mozart or Beethoven - even though there is a lot in it which i probably will only highly educated and talented people will 'get', most people can easily find something enjoyable in that kind of music.
Drinking Fukamushi often reminds me about listening to more abstract, more modern musik - lets say Shostakovich or even Schönberg. Its not "better" or "worse" music than the others, but if you hear it for the first time, chances are that you won'*t appreciate it right away. Its less candy-like, it has fewer of these elements which please you right away, you need to get a certain familarity with it in order to appreciate is aesthetics.
Of course that metaphor only works so far
