Precisely. It's not just about national rankings (Russian #1 vs. US #3). H/D's SD this season was widely acknowledged as a huge step forward for them and one of the standout SDs of the season. The sheer fact that one team is internally ranked higher than another means little, IMO, because those national rankings depend on the depth of the field in their countries, and right now, Canada and the US have incredibly deep fields. (Although, I would be surprised- utterly delighted, but surprised- if H/D surpassed C/B next season. I'd love it, but it's probably not happening. Sigh.)
As far as the Russians go, I admit to being slightly biased in favor of I/Z as my personal favorites; I find their skating the most unique and exciting to watch, and I think they are actually well-matched: even if Elena is always going to be a naturally stronger skater, Ruslan is a good partner. Their issue, from my uneducated standpoint, is primarily consistency and coaching secondarily. That lack of consistency has cost them big, and they have a fight ahead to regain the judges' favor. That said, there is no dominant team right now, which could work in favor of any team that manages to get two strong programs in the same year. I think B/S could have done well at Worlds if not for the meldonium scandal, but I fear that the fed may decide they're out of chances. S/B are lovely enough, but I don't find much potential to leave a mark; their programs to me are like running water: pleasant in the moment, but slipping away from memory before you know it. S/K don't do it for me at all; their programs always seem... self-satisfied and smug, I suppose, and Nikita's twizzles are the stuff of meme. But all this is just my opinion, I claim no expertise!
