Unless it's magically gotten better since then.

Its gotten alot better then the early days. In my experience x265 have no issue with grain and fine detail, and is imo better then x264 at ”normal” levels (crf18 ~6-9Mpbs if we are discussing 1080p SDR). The issue is that it needs at least preset slow (combined with no-sao and some deblock), and that makes it much slower then x264. I have yet seen x265 be tuned at then same speed as x264 (slower/veryslow with tune film) with better detail retention.
With that said, is x264 better for 1080p sdr to achive near lossless quality at high bitrates? Sure, especialiy if speed also is concidered. But that is not the focus for x265 or most hevc encoders.
