Use cases seem to still bring value over stickies:

"I also want to thank you that the use case document helped a lot in bringing the team together in discussions and covering holes. It also made me understand better and get inside the room through the objections and working together. We're now close to send it to the customer and I can confidently own it."

(Me:) "am super glad the written document helped improve the discussion over just the sticky notes :)"

"No comparison"
