I'm going to remember this episode for a long, long time for all the right reasons.

The moment when almost everyone is back in the prime timeline and Picard orders the self-destruct cancelled? Chills. Peace with the freaking Borg. Seven in the captain's chair. Seven and Raffi kiss. Rios gets his happy ending. Elnor gets another chance. Q gets a hug. Wesley Crusher! Also love the bit with Soong setting up his descendant's story in Enterprise.

Also, I really like the bookending with Q + Picard + the Borg + Guinan. The day Q flung the Enterprise into that encounter with the Borg, it was ultimately in dialogue with Picard and Guinan. And Guinan even noted "perhaps when you're ready, it might be possible to establish a relationship with them". 36 years later (2365->2401)...Guinan was right.
