I am glad that the Remake greatly reduced the rivalry between the two girls. It shows that friendship is much more important than jealousy over a guy. Wouldn't really fit into our times, anyway. And I don't think that a character's (a woman's at that) importance hinges on whether the (male) protagonist is romantically interested in her. Not anymore, those times are over, fortunately.
Aside from that

When I played the OG for the first few times, I still remember feeling a much deeper emotional connection between Cloud and Aerith and even seeing them together in a romantic way, for all the flirting and everything. I don't feel or see any of that in the Remake. Not even in the few "Clerith"-scenes we get. Much more I feel a brother/sister/close friends-bond between them.
And the huge addition of Cloti-scenes we got clearly points in one direction and one direction only to me. Plus Aerith still dies and if she should really turn out to live by some highly unlikely fate/ timeline-sheenanigans then by all rights, Zack should live as well and if that happens, the pairings are all the clearer (not saying it will, I don't think that's realistic).
Well, I can just describe my own feelings and they are pretty clear.

But I still respect other opinions, of course.
