I actually like them both, but Lwaxana paired with Odo is funny.

Odo & Lwaxana were awesome funny together and I like them as friends :) But as a couple there is only Odo & Kira for me!

Odo & Kira all the way! I think that Lwaxana saw that Odo, when he loves, he loves fiercely ... with all that he is ... and he LOVED Kira. She saw that love in him way before he allowed himself to acknowledge how deeply he loved Kira, and saw that even after all the turmoil Kira's relationship with Shakaar gave Odo, he still loved her ... and was waiting for her. He never directly answers her when she says, "Are you over her?" He evades the question. I see Odo and Lwaxana remaining good friends ... and know Lwaxana would be thrilled after finding out that Odo and Kira had gotten together. MBR once said at a convention that Lwaxana had a "crush" on Odo because he was different from all the men she ever knew and was refreshingly honest. But that Odo's true love is, and would always be, Kira. "The writers got it right. Eventually, they [Odo & Lwaxana] would have both been unhappy."

Turning Lwaxana down at the end of "The Muse" proved that Odo wasn't looking for any relationship, nor was he willing to have a fling with Lwaxana as a way to get over Kira. Odo loved one woman and one woman only, and neither time nor circumstance was going to change that.
