I think it depends of how much you like a character. I hate the current emma, but I loved her in Gen X, also, if this means to break scott/emma I will be happy since I will preffer scott with any other couple by now. Also I think that scott/jean problem was taken out of proportion to fit the story, they were a couple with more than 12 years of marriage (if you count the time they time travel) and raised a child together, that is why I still don't like that run and heven't read it.
They were having "issues" in Seagle's run and were clearly not happy (after being completely boring and having no chemistry all throughout the 90s - with him hitting on Psylocke just prior to their wedding). Jean had to fake hints of a fake pregnancy to keep his attention. Then he "died." Then he blatantly avoided her for the remaining Lobdell issues. We had him completely ignore her, despite the fact that she and Cable saved him from Apocalypse, by going camping with his dad. Moreover, he then left for Genosha with Wolverine. Then Casey showed him freezing her out, literally driving her into Wolverine's arms. THEN Morrison came along.

Apocalypse is Father and the Phoenix is mother imho. Apocalypses descendants have physical mutations while the phoenixes descendants have psychic powers. Now mix and match and interbreed them for 5000 years and PRESTO, mutant race with endlessly diverse powers.

Still, it was pretty clear to me that Scott and Jean weren't very happy with one another. With the absence of a crisis to distract them, they were pretty miserable together.
Though he's cowed by Emma Frost, Scott seems much happier with her.
I always viewed Scott and Jean as that High School couple that got committed too early and always over idealized each other. They love/loved each other, but they could never deal with real relationship issues. I think had they retired from the X-Men they might've had a better shot.
