According to my own biased personal opinion:
Oxxford missing from the list and should be in the top section. Battistoni another brand that should be up there.
Tom Ford and Zegna Couture should be right at the top section. I personally would not hesitate to put either in the illustrious company of the top group.
Z Zegna is fused how it outranks half canvassed suits I will never know unless going by fabric.
List lacking brand whore brands:
Gucci deserves a place somewhere in the better sections of that list, Prada (certainly the Belvest made stuff) is pretty dang good, Bottega Venetia, Lanvin, Dior, Mcqueen and a few other fashion brands deserve a mention. Most, if not all have at least a few fully canvassed models in their collections. Not sure about the omission of Hermes either, suits I have seen have been Belvest made judging by tags and they aint half bad - at least in Very Good category or actually in the top list.
Armani Black Label is too low, should be in Very Good category. Something is wrong in a world where Corneliani or Canali rate better than Armani Black Label. Armani may be brand whore fodder but they dont make shit (at least in the case of Black Label or "Blue Label Classico" stuff). Armani black label is fully canvassed and some suits I have seen had most, if not all the bells and whistles one expects from a high end suit.
