You're gonna be bothered by how cool I am.

You know, I've always called myself a R/Hr shipper first, but the last few weeks have really made me realize all over again how much both ships matter to me, because one without the other feels really incomplete. In general I am very happy to compare and contrast them because they have been realized in very different ways, but it does make me a little sad when I feel like somebody is trying to paint one as superior to the other. My emotional relationship with the series has really grown to involve both and I find the total coming of age arc really far more satisfying with both in there; I can barely imagine one without the other at this point.

I feel kind of annoyed sometimes when people talk about R/Hr as the "real" romance of the HP series.

I think it's fair to say that R/Hr has been the "most prominent" or the "most developed" romance in the series; those seem like factual statements to me, just judging from sheer quantities of page time. R/Hr was evident earlier than H/G (there was H/G foreshadowing in CoS, but the actual R/Hr romance appeared sooner) and developed more on-page. So those things I would be willing to agree with.

But I also don't particularly like saying one is the "real" romance of the series, since that sounds more like a value judgement that doesn't have much content other than to put the other ship down. I feel like in books 6 and 7 put together, we get to see how both relationships can be sweet and wonderful and we also get to see both relationships under stress and strain. But since HBP was more stress for R/Hr and then they finally got the sweetness in DH, I think that is what is most prominent in people's minds right now. I think a lot of people who are R/Hr shippers first are just really happy with the way it was realized, but I agree with you, I feel sad when I see H/G being put down at the same time.

people seem more interested in R/Hr than H/G now

Oh, not me. I am much more interested in H/G at the moment. R/Hr was ♥ but I feel like Jo resolved it so wonderfully there's not much more to say. With H/G it was left very open-ended, we know they got married and lived happily ever after in the long term but really have no idea how they got back together or what things were like between them after being separated for so long. The details are not filled in for us and so I find myself thinking abut H/G much more.
