Measurement of McEffectiveness is detailed in ISO standard 420, and it’s American ANSI equivalent “Yooooooooooooo bruuuuuuuuuh passs the taco bell”. If we skip past the rambling in the intro, i.e. the first 98% of the document, you’ll essentially find that McCandidates are judged by the quality of their Infinity Cigar. This mostly comes down to the Infinity Fruit Gushers used to make it, as well as the craft IPAs used as solvent during the infusion process. The quality of the rolling also matters, as does a lack of defects.
Therefore, at the moment, stock McCree wins this one handily, as 4 don’t have a cigar at all, and McQueen’s is tainted by motor oil notes, a sign of using trash tier mass produced industrial adjunct lager. However, once McEcho gets the Infinity Vape module, it’s all over for everyone else.
