Hopefully this can spark discussion regarding style, construction of the face, and personal preference.
If you know me, you know my favourite styles come from Toriyama, Maeda, Aoshima, and Satou in the 80s. The anime looked the best from 1987-1990 in my opinion. Super: Broly is a nice homage to the old stuff while having modern Toriyama's wider and simpler faces.
Takahashi also tried to draw the various styles of Goku:

My guess is Shintani 2018 (Super: Broly), Toyotaro 2017 (Super Manga)/Toriyama 1996 (End of Z), Toriyama 1989 (Saiyan arc)/Maeda 1989 (Saiyan arc), Yamamuro 2015 (Super), Satou 1990 (Frieza arc), Nakatsuru 1996-1997 (End of Z/GT), Toriyama 2018 (Super promotional work), Maeda 1990/1991 (End of Frieza arc/Cyborg arc/Cooler Film).
