I would say her characterisation and story-telling is superb, but I wish she would just elide the science elements of her science fiction because like, she sometimes get basic science wrong, and there was no reason to, she could have just elided it - most authors would have! There's an lengthy and entirely unnecessary (nobody asked!) and irrelevant explanation of how a robot's power system works in one book, and how it's not a perpetual motion machine - except it completely 100% is a perpetual motion machine! Because she's doing science by analogy not science by science, and like why not just say it has a basically de facto eternal power supply? I would never have questioned that.The only science fiction author today where I preorder their books, sight unseen, is Becky Chambers, but again, I'm not sure if I could say her work is the pinnacle of the genre. (Although it's very, very good.)
That said if I really care that much about getting science right there's always Mary Robinette Kowal and the Lady Astronaut series, which have almost depressingly hard and accurate science.
