Tore... the reason people think it "feels/sounds" better is a placebo effect as a result of their misguided mystic fantasies, and nothing more.
It's not relational to, say, using a capo transposing a half-step up on an acoustic guitar simply for the change in action, resonance, and tone.
Theirs' is a mental thing.
The only reason for transposition of a tuning to any different frequency would be simply for audio acoustic advantages only... For instance, if you notice that in a particular environment, (a) certain note(s) would always resonate louder than others due to its relationship to the acoustic environment and standing waves, you may consider transposing some cents worth of degree. But eventually you just get the same problem in different notes. Generally people just treat rooms to diffuse, deflect, or absorb excessive waves.
That said, there really isn't a valid reason for transposing to 432hz unless you just happen to like the way you think it sounds, which is not much different, given the small difference from 440hz.
I dunno... People will be people. You can't be surprised that someone comes out with stuff like this 432hz crap and it spreads. If history is a lesson, then you should have your Doctorate in spotting these jokers.
