Do you mean in terms of like... are you asking if "she was happy" is easier to read than "her face lit up as she squeezed his hand excitedly"? Like that the first one is simply Telling rather than Showing and thus easier to read but doesn't provide the description of the second?
I'm curious what specific types of writing you're intending here because I see a lot of folks seem to be thinking of "exposition" as when you do a big infodump of like.. the history of the world or whatever, but generally you don't replace that with description in order to make it better; you just... weave that exposition into the story more naturally to make it better.
There's also the possibility that "bad writing" is popular in spite of, rather than because of, these factors.
Like, between a well-written story that's decently in your range of interest, and a poorly-written story that is THE EXACT SCENARIO AND CHARACTERS that are 100% your jam, a lot of people will gravitate towards the second one -- not because they like bad writing, but because the bad writing doesn't put them off of something that resonates with them so strongly.
I think a lot of times when "bad" things become popular, it's because they're tapping into something that a huge percentage of people really wanted to see or experience in that moment, and for a lot of readers, a writer handling exposition optimally is kind of secondary to the experience they're providing.
