I have a feeling people who love Le Guin love the idea of her and didn't actually read her books. Her style is impersonal, robotic and kind of boring. Look at her most famous quotes for a snippet: https://www.goodreads.com/author/quotes/874602.Ursula_K_Le_G...
I think judging her by the most popularly-upvoted snippets on Goodreads is doing her a tremendous disservice. Her language is not particularly flowery, and she writes using simple words, which are often the ones that have the vaguest meanings and the most room for nuance. If you take a single sentence like that from a story or novel, and remove it from its surrounding context, you strip away a lot of that nuance. By reading the sentence in isolation, you only see a pale shadow of its intended meaning.
Maybe this is a bad analogy, but it makes me think of how you wouldn't think there was anything interesting about Tchaikovsky's 1812 Overture if all you heard was the cannon volleys by themselves, even though they're what make the piece complete.
