I think this debate always leaves out the fun factor that some people have more fun doing a trick a certain way therefore seems easier. It's not that something is harder per se you have to consider the skater thinks a certain trick is wack if it's not done switch or vice versa....or they mastered it regular before they started filming and then started skating switch to be sicker and only film it switch, nothing to do with awkwardness of attempting the trick, more about style and attitude.
I'm not a fan of the debate to scientifically debunk switch skating...maybe scientifically addressing your actual stance I can get down with, but I don't think to this day there is a defining reason about goofy or regular foot. But for switch, nah switch is switch, nollie is nollie, fakie is fakie, which IMO, historically, is based off of style and attitude.
