If I was Ben, I would have asked about the advantages of making boards that are square as fuck with shoddy craftmanship. Schmidt can talk all the science he wants, the inconsistency of PS Stix manufacturing nowadays is nothing to be proud of
^^^^^^^^^^^^^^^^
It's kind of insane that Paul clearly knows what he's talking about, but the quality of PS decks tell a different story.
Also saying that epoxy is inferior to wood glue because it's harder so it breaks easier was worded so weirdly and something I don't fully agree with (although someone with more woodworking experience can chime in). I understand that he means that wood glue will let the deck flex during impact while epoxy won't, but I've had way better experiences on NHS decks (uses epoxy) than PS Stix decks in terms of durability.

OSHA's going to have a heart attack when they see this video :v
It's not super straightforward and both wood glue and epoxy work fine. It really depends on what type of epoxy is used and what type of wood glue.
Epoxy fills gaps a tad better, which should matter with a skateboard, is really strong, and tends to have high sheer strength. In some niche woodworking applications some people find that it can tend to crack during twisting or really rapid applications of strength. I had something crack at the glue line once, but it's not a common problem. The advantage is it can cure faster and often times needs less clamping force.
A lot of people use it when the glue might be exposed because you can dye it to match a color and it finishes nicer.
Wood glue can be stronger depending on the glue, way it cured, and clamping force. It can resist twisting slightly better in some applications. Personally speaking I've been unable to break anything I've wood glued.
In the end it doesn't matter much for a skateboard. My guess is that boards made with epoxy take less time to produce since they can cure faster and need less time in a press. Probably helps the Chinese companies mass produce things easier.
