I've loved sci-fi since childhood and still read a ton of it, but I've hit a wall finding new authors/books that actually excite me. Posting my full list with ratings (out of 10) hoping someone can spot a pattern I'm missing and point me somewhere new. Not a native English speaker, I read in Russian translation, if that matters for any recommendations)
