I hate the term 'rolling'. It's an American import. We should be doing comparisons. The only thing I roll is cigarettes!

Ha - in Glasgow 'tube' [pronounced as 'choob'] has a rather different meaning! In that respect, 'choob rolling' could be very interesting...

The original Siemens [IMHO] are by far the most "Right" sounding of the ECC88,E88CC,7308, 6922 Variety.
But, as others have said, it will depend on your taste, and system setup, be careful of NOS versions, as all the variants of these valves tend to suffer badly with noise issues, [they werent paticularly designed for Audio purposes] so, be sure they have been tested properly!
Good luck on your quest!

Oh my god! There's nothing wrong with the bidet is there?
“Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".
“You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”
"You don't have free will. You have the appearance of free will.”

I do! and "rolling".... We're British FFS!I suppose you hate the word tube as well.
Also PCC88 is not really compatible with ECC88. It has a 7V heater as opposed to 6.3V so whilst both will work it's not ideal. For optimum performance and reliability heater voltages need to be fairly accurate, believe it or not...
As Anthony said the ECC88 was not designed for audio use (VHF cascode RF amplifier is its intended use) and so they are not really tested/graded for low audio noise. They can be one of the lowest noise valves in general use but you will find lots of rogue noisy ones around which, whilst they make the grade for their intended use, are way too noisy for the first stage of a phono stage for example. "Good makes" can be the worst in this respect (ie that out of say 10 valves 3 may be noisy) and Russian ones often the best as far as consistently low noise IME.
