Bug Bite or Fury Cutter Pinsir?

They are about equal, both are easy to dodge with. But I would go with Fury Cutter, because of how fast it charges X-Scissor. Also, it's legacy.
But, Bug Bite isn't a bad move. It is one of the better EPS moves, it just happens that Fury Cutter has higher EPS/generates energy even faster.

Yeah like DragSlaya said the are about the same; FC has a slightly faster cooldown and EPS gain whereas BB puts out slightly more DPS
