I think if we go by portrayal, their attacks should rank like this:
- damned punk
- puncture wille
- Punk crash
- shock wille
- punk corna dio
PCD should be weaker than shock wille as it isn't an awakened technique and linlin's reaction and words indicate shock wille is stronger. I think punk crash should be stronger than shock wille, imo it clearly did more damage(compare how bruised she was before vs after) and it was harder for linlin to recover from.
PCD should at least be comparable to an ACoA kong gun imo, it forced linlin to dodge the second time and probably contributed to linlin's broken bones.
