I dunno about machines and the SG w-o-w-o or P21S as a) I don't use w-o-w-o and b) I seldom use P21S But generally, I don't think too many people are gonna do as good a job, start to finish and every time, as the PC will. All those orbits per minute, every time, never getting sloppy or tired...Besides being easier (at least IMO), I believe that most people will get better results, or at least more *consistently* good results working by machine.
Most synthetic products (Klasse, NXT, Zanio, etc) require a super thin application for optimum results, a machine / foam pad provides a uniform pressure and enables a very thin product application.
I’ve never used the WOWO method for product application so I can’t really speak to it

If we are talking pure wax on a properly prepped surface then I highly doubt it matters. I chose 'by hand' simply because I can do it more quickly and use less product than by machine.
No..... This is pure wax(Carnauba, Montan and Bees waxes) with no fillers, by using your hand you will not waste the product. You want to put very little on and by using your hands you can control the amount. I am told the heat of your hand is the first catalysis in the bonding process. There's nothing like the hands on feel and results.
I prefer to wax by hand. I feel there is much less risk of putting any swirls in the paint. You also save the money that you would spend on the machine.
