I think that Riker's story in Best of Both Worlds is both a triumph and a mistake. A triumph because you see him finally step up and take the big chair and make the big decisions that go with it. It was a mistake because for his journey to mean anything, he would need to end it by actually becoming the captain of a starship. Instead he just goes back to being Picard's first officer and it cheapens the whole thing. Riker proved that he was ready to take command of the Enterprise and Frakes proved that he had what it took to carry the show. Michael Piller shouldn't have created this story for Riker unless he was sure that either Patrick Stewart or Jonathan Frakes wouldn't be returning to the show. This story was Riker's definiing moment on TNG and after what he accomplished, its unrealistic that he would have been satisfied with anything other than command of his own ship. I don't think the most important conversation was with Troi. I think it was with Guinan in Part II. "That is now your chair....Captain." They went too far just to pull back and pretend it didn't happen.

I happen to agree that Riker becoming captain, then going back to first officer, of Enterprise is a bit unrealistic.
Riker was one of the choices to be captain of Voyager, though, as revealed in the ep with the two Q's. How different would that show have been with Jonathan Frakes as the lead? That never would have happened given the lucrative movie deals he'd pass up, but still.
Once, I posted a thread postulating how Riker could have become the lead in DSN. As you all may recall, Sisko's mother wasn't his mother, but some kind of Prophet/wormhole alien in disguise, making him the Emissary.
But suppose the wormhole aliens, able to see all futures, bought an "insurance policy" and had more than one emissary-in-waiting? Riker's mom, Betty, died early, too, so a wormhole alien might have conceived him with Kyle Riker, also dissguised as his real mother. Then he would have become the emissary, or "the Riker, there can only be one."
Just a thought.
