Actually, now that I mention it, even just by episodes that don’t focus on pairs, I rarely see Rarity with any other character that isn’t AJ
And to be fair, Rarity and Applejack don’t always get along that well either, for a lot of the same reasons Rarity and Rainbow had issues. In fact it’s kind of interesting to think that the friend Rarity probably gets along best with is Pinkie Pie, and I can’t help but wonder if it’s because they both are similarly driven by a particular passion. Pinkie’s purpose in life, after all, is making ponies happy through parties, and Rarity seems to thrive on a similar goal, which she achieves by helping others look their best. I think it’s the sort of thing they just “get” about each other, which might explain why they seem to tolerate each other’s rather excessive personalities fairly well.
Actually, thinking about it, they may be the only two who
do appreciate each other’s respective passions. Rainbow really only seems to care inasmuch as she has the best of each (biggest party, coolest outfit, etc.), Applejack is mostly focused on practical (the only party I think we’ve seen her throw was to bring her family together and/or build a barn, and her clothing interests are mainly involved in utility), and Fluttershy seems to not think highly of either (lest we forget the time she became super assertive and called Pinkie and Rarity out on their “frivolous” interests). So really, they might be the only two who truly understand each other that way, which explains why a lot of their time together feels so… unforced.

Starlight’s biggest damn blindspot is herself.
In some ways I think her biggest failing has become being too hard on herself. I mean, look how many of her problems since reforming have been caused her by holding herself to a standard she thinks others expect, rather than the one they actually do. Trying to do all her friendship interactions with Twilight’s friends at once to impress her teacher backfires on her. Trying to be the school headmare she thinks Twilight expects backfires on her. It’s really a case where she needs to learn that no one is suddenly going to revoke her friendship card if she doesn’t constantly make impossible levels of progress.
