Episodes that have no clear 'A' story

[at Quark's]

In many episodes, there;s an 'A' and a 'B' story (and sometimes even a 'C' one, etc). Most times, it is pretty clear, either by screen time or 'drama' or potential implications for the rest of the series which one is intended as the 'A' story (for example, in DS9 some structural development in the Dominion War vs. some trifling drama for one of the protagonists that is not revisited after that episode).

I was wondering if there are exceptions to this? Where it really seems like two equally important (or: equally unimportant )stories are being played out, and it's kind of hard to say which one, if any, was intended as the 'A' story?

TNG as a format choice had ensemble episodes with multifocal parts like Disaster, or Lower Decks & also fully multifocal episodes like Family or Liasons

And then they developed a format that featured dual storylines like Thine Own Self & Birthright 1 & 2

More like Birthright Part 1. There is nothing but Worf related story in 2.

"Cause and Effect" only has an A-story.
