based on my personal tier list, and adding up the scores, I get
>genwun
61+26
>gen 2
46+3
>gen 3
42+17
>gen 4
54
>gen 5
39+6
>gen 6
56+0
>gen 7
41+7
>gen 8
34
>gen 9
26
(separating the later-introduced altforms into the second numbers)

Which would make
g1 > g6 > g4 > g2 > g3 > g7 > g5 > g8 > g9
at base, and including alt forms, would only vary to
g1 > g3 > g6 > g4 > g2 > g7 > g5 > g8 > g9
