At the beginning of TNG Worf was still quite a Klingon, eager and easy to provoke. His dealings with Q and Lwaxana was a big trial of patience. Sometimes Worf seems to me more serene and composed than Sisko. Sisko became more and more Klingon. He even turned into one in an episode.
Nonetheless I'd like to have seen Deanna in a guest role aboard DS9. If only to chat with Ezri about the trials and hardships of being a counselor. Deanna has Reg as difficult patient, Ezri dealt with Garak. But I guess it didn't fit into the Dominion War storyline.
I had the opposite feeling sometimes. Worf seems to be more klingon, and less tolerant of others than he was in TNG, in some DS9 episodes.
Maybe it was, because DS9 not being a starfleet installation that made him hold onto his klingon identity even more than he did during TNG.
