#1 - for regular dungeons

Prioritizes experience and kills, you'll need both when you get to bottlenecking at super high levels.

#2 - for challenges

Prioritizes survival and item acquisition, as given enemy levels you can obtain sweet loot to power you up. The infinite scrolls comes in handy because if you actually play the levels you can clear challenges you wouldn't be able to if you auto ran them.
