I must have scored the Reflektor high in most areas at the time, it is more like in which areas did other tubes rate higher or lower or the same. It is more about accurately covering the entire audio spectrum and not lacking in bass mids and highs, separation, soundstage, etc. We use music especially recorded to show off the traits we are looking for and at times we use the same system with a group of fifty. When all is done a tube might rate as much as 100, (it has not happened yet) but scores in the high nineties have been recorded. I believe all three types scored well and maybe you like more bass, or airiness, or advanced mids so it still boils down to what you like with your music.
I have a hard time finding tubes that match up well with Focal Utopias, often the high frequencies are lacking, not so much with Reflektors IMHO.
Someone else mentioned Brimars, I merely said my favorite was the 1975 silver shields.
