Lastwhisper effects are on first hit and all enemies while BC requires you to hit the same target 3 times to get maximum effect. I do believe that alone means last whisper wins. Regardless you only need a decent amount of armor pen for one thing and that is for tanky champs who will have copious amounts of armor.
