Hhmm.. guessing here cause I haven't used all of 'm.
2 & 3 have that distinct neve buzz in the mids and are a bit nasal in the mids so I'm guessing these are the Vintech & Great River.
1 & 4 lack that iron buzz and are my favorites with nr 1 having more air and nr 4 being more in your face. So I'm guessing these are the Pacifica and buzz.
I'm going on one limb here and give it a go:
1: Buzz
2: Vintech
3: Great River
4: Pacifica
You can start laughing now
