"Wow! I guess this must be true because these smaller "boutique businesses" have more money and better connections so they can buy the "higher end ingredients" that the big companies with millions can't afford/find? Obviously these big companies wouldn't be able to dictate how large or small of a batch run they want because they're so big, right?"
Wow, where to begin...smaller companies, particularly owner/operators, often (not always) put more care into their products. They can also serve a more upscale niche market like Pinnacle that is selling $70/jar waxes. On the other hand, larger companies often go for larger markets where emphasis may be more on value and distribution than pure results. Megs actually does a decent job at both as does Mothers which is much smaller but in my personal experience this is an exception.
"But there is no way that Souveran or P21s lasts as long as #16, Blitz or Collinite."
Yes, but it kicks butt looks wise over these.
I routinely got 6-7 weeks last year in the heat of July Atlanta sun with both P21S and Souveran.
Let's look at the empirical evidence from Guru Reports:
(Durability scores from Wax Test)
Megs#16 C+
Collinite 476 B+
Collinite Marque D'Elegance B+
Blitz One Grand C+
P21S B-
Souveran C
Looks like they did well in this test versus others.
