Thermalright Peerless Assassin or Assassin King?

Which would be better to cool a Ryzen 7 7700? I do a lot of work on my PC so the cpu is usually under pretty heavy loads, so which one would be better too cool my cpu?

Currently the AK is $25 and PA is $43. Is the PA worth the extra $18? I've seen a few benchmarks where these coolers only produce about 0.5C difference.
