I assumed this would be easy as both seem perfectly legal. but G23 says...

<G23>
SUPER CELL scoring – During the last 20 seconds of the MATCH, the PAYLOAD SPECIALIST may launch the available SUPER CELLS over the Alliance Station Wall and into the CRATER. The PAYLOAD SPECIALIST can SCORE a SUPER CELL by launching it into a TRAILER. If a SUPER CELL is launched into the CRATER before the last 20 seconds of the MATCH, then two (2) PENALTIES will be assigned.

The way it is worded the Payload Specialist must launch it into a trailer. It says nothing about a robot retrieving the Cell and scoring it even though that seems it should be a legal method of scoring
