You're using too many reference frames. 16 is way too much, even for anime encodings. Good values for feature films/film series is between 4 and 6. Anything higher is not beneficial and can actually degrade quality for live action content. For anime, you can up it by 2 more

As for comparable settings for x265, that'll be ref=6:subme=5:rd=6. However, there are other things to tweak like psy-rd and psy-rdoq. I like using high values for these options (psy-rd=4 and psy-rdoq=16). A qcomp of 0.7 is also nice. Also, using aq mode 1 seems to give most of the time the best subjective quality. The other aq modes are too unpredictable and some just waste bits for no apparent image improvement
