Indeed I imagine Frontier prefers there to be no best way, given the quite active responses to balance various actions! Generally the Power kills seems to be around half that Rare commodities rate, or a bit more if combined with Search and rescue in a Reinforcement system, but at this stage I imagine it becoming more balanced later.
Power kills also have their moments; some interdictions are just a single ship worth 53, some are hidden high-value targets in a low-rank and often no-shield ship but worth over 100, and some come with wings and passing convoys which can be slain merrily for several hundred total!
Generally I just want to do Power kills, where secondary Search and rescue is something I can add to be a bit more efficient, but if all of that will always be a league below something else then I would finish the little undermine project I started, do the laziest thing I can to reach rank 100, then stop.
