I think for teams like Tech and OSU, Park would be the better quarterback as he has a more gunslinger mentality. But for the other games, I think Kempt will be fine.
When you play teams like Tech and OSU I would argue that a gunslinger plays into their favor. The recipe to beat those teams is long sustained methodical drives to keep their offenses on the sideline and throw off their rhythm. Both Tech and OSU would rather play in a track meet.
