Value? Columbus. That said, there are so many things that can't be answered yet. Will both players (sry Roslovic) extend and for what money/term? How does Laine fit CBJ system? Can Dubois reach that next level now that he's not the #1 center, but gets to play in a more open system? How will CBJ look now that they don't have that #1C and arguably not even #2C (unless Domi gets himself going)?
It will probably take a couple years to evaluate this trade (this one more than most). That said, given what situation PLD put Kekäläinen in by his antics and Torts benching him, CBJ made out like bandits IMO.
