>>36791008These OP's never specify if they're talking about Base Forms, Final Stages or Overall Lines, so since it ain't specified and i'm bored as fuck, i might as well pots the best of each.
Gens with best 1st stages (best to worst):
Gen 2>1>6>7>3>4>5
2nd Stages:
1>7>6>3>5>2>4
Final Stage:
4>6=3>7>5>1>2
Overall Evolutionary Line quality by gen:
6=1>3>7>4>2>5
I'm bored enough to want to detail explanations behind my rankings, but fuck the character limit.
