My tastes run towards simplicity.
While I appreciate a well-crafted turn of phrase, lyrical word-smithing is not a requirement and overly lyrical prose will raise a caution flag. Unless the book is well-above average, I would be less inclined to return for more from the same autor. Especially if word-smithing is most or all that the author has to offer.
Conversely, I look favorably upon authors whose prose is lean and concise and who get to the point easily. Even more if they have a worthwhile point to get to.
Examples? I favor Asimov, Heinlein, Dickson, and Anderson over Ellison, Bradbury, Moorcock, and Delany even though I have read, enjoyed, and own many titles from all of the above. Thus I am more likely to reread books from the former group than the latter.
Ideas over mood, basically.
Worldbuilding over pathos; plot over theme; rationality over neuroses...
