There is a lot of hype about tubes. Keep this in mind. Whether a tube is a 6L6, 5581, EL84 or whatever.... they all must have a standard set of parameters to make them fit into their category Grid voltage, screen voltage plate voltage and so forth. Naturally those specs vary. But not so much as the other components in an amplifier.
Groove tubes are over hyped in my opinion. You can buy manufacture sets that are matched for far less. I have never noticed much difference whether they are perfectly matched or not.
Consider this. The output transformer winding's are not perfectly matched. Neither are the resistors and capacitor in an amplifier. One of the things that most likely give vintage amps that special sound may just be the wide range of tolerance in components. When a resistor is marked 20%, as a whole lot of them were in old amplifiers, that means there could be a 40% difference in the same value resistor or capacitor. Even today electrolytic caps are generally off 20%.
Just buy an amp that sounds good to you. Most of the brilliant ideas you get from the internet come out of someones ass, not an oscilloscope. I know that people swear there is a big difference in components. Ever hear of the placebo effect? Generally some manufactures have better builds like anything else. In over 50 years of repair I have not been able to hear the spectacular difference some people claim. But to each his own.
