I don't have a preference as long as the writer is creative and competent. Attention to detail matters, though.

You can dream up whatever future technology you want, but if you don't think through the societal, economic, and even social implications of that technology at least a little bit, I'm going to start to lose interest. I like The Expanse series (hard sci-fi) for that specific attention to detail. On the fantasy side, I like the Mistborn series for the same reasons.

Sci-fi I didn't like was Red Rising (which was just another flavor of Hunger Games with the same boring anti-elitist enlightened-centrist stance) and Cyberpunk 2077, whose every idea and theme felt half-baked.
