WTF 10! Why is this a debate?

12 for sure, I just want to be hit on by Riker.

Seat 9. I’d say Picard and Chakotay would be pretty mellow and level-headed unless Chakotay’s feeling extra resentful about Picard’s handling of Marquis/Cardassian Neutral Zone stuff. It’s then insulated from some of the crazier pairs with level-headed duos, or at least balanced duos (e.g Raffi and Spock or Kira and Progeny). The exception might be Sisko and Kirk, who would either get along quite well or drive each other to the brink of insanity. Either way, (1 assassinated Romulan senator later) I can live with it. Though maybe after the first hour, I’ll have seat 12 to myself after Riker and Kelvin Kirk go to sick bay for competitive chair-sitting-related injuries…😏
