I like Scott and Emma because they were a dynamic, contrasting couple which enriched both of them, especially actualizing Scott as a much more assertive, confident leader of the X-Men. It made them both multifaceted and better. And it's never been nostalgia, because a) I read Morrison's run as an adult, I grew up with Claremont and b) many of my favorite moments for them came post-Morrison. YMMV, but I don't have anything to prove or justify.
