Hmmm, I enjoy all four quadrants of energy/urgency:

High Energy + High Urgency = super exciting, go go go, you have time for one last exchange with the Prince before the bomb goes off/he marries another

Low Energy + High Urgency = very thinky, an in-game puzzle or the meta activity of figuring out how to mechanically do something (building or applying your dice pool)

High Energy + Low Urgency = silly fun, a mook fight, lots of stunts, a glittery party with many conversations.

Low Energy + Low Urgency = quiet moments, a conversation between PCs that doesn’t advance plot but does reveal character.
