It's a hobby. And a hobby with lots of snake oil, opinions that are not based in basic electronics and general B.S. So rather than get some opinion of what tube sounded good in what amp, why not start with a bit of simple, basic, theory so that you understand the parts of the various tubes and how they go about their work? It's much more painless than it sounds and you will know more when you are done than 99% of the experts out there.
The beginning, as far as I am concerned, is one of the versions of the RCA Receiving Tube Manual which was updated annually for many years. There are some reasonably priced reprints available, and original copies on ebay that are not too expensive. If you want to have a look, here is a pdf version for free:

I wish you the best of luck in the enjoyment of the hobby and your journey into valve amplification.
