As to the weight and other factors, yes sometimes what could appear to be even the same boards can feel significantly different, some heavier some lighter, some thicker and some thinner.
Exactly why, who knows. Especially given the quality control that goes into making skateboards these days, but the best wood is used for the pro boards and the other wood is used for the pricepoint boards, so it stands to reason that if you can afford it, get the pro boards more so than the pricepoint boards.
Some people I used to skate with would snap a pricepoint board in the first or second session and if it was still in one piece, it would often feel so soggy, when compared to a pro board that would usually last them a month or more, nearly every singe board.
Other people have skated them hard with no issues the whole time, only retiring it when they felt like they wanted / needed a new one, so it is funny like that.
