Feint Attack or Razor Leaf on Shiftry?

Their cooldown is the same, with Razor Leaf dealing higher DPS and Feint Attack more EPS.

Feint Attack/Leaf Blade seems to be its best moveset for neutral damage in PvP. The typing does also matter of course, if you find yourself using it more against targets weak to grass than to dark, stick to RL.

Feint attack is the generally better move. It gains energy 50% faster than razor leaf while dealing 33% less damage. And Leaf Blade is a pretty fantastic charge move that you'll want to charge fast.

Neither Feint Attack nor Razor Leaf generates energy quickly, which is a real hindrance for Shiftry. Feint is kind of average at 3 EPT, while Razor Leaf is near the bottom of the pile at 2 EPT.

Leaf Blade is great, but better to feed it with the fast moves that Sceptile has.
