so, for my taste, the answer on the question "what tuning is better?" - the answer is "depends" !
@IgorHawks 432 sounds mellower than 440 in the video. Pitch inflation has occurred throughout history https://en.wikipedia.org/wiki/Concert_pitch#Pitch_inflation
and it's only getting "worse" https://music.stackexchange.com/questions/776/why-are-orchestras-tuned-differently
