Casey is a frequent guest on his shows. It's hard to not conflate the two.

Prime is an entertainer first and foremost. He talks with confidence, even when he doesn’t know what he’s talking about - which is very often.

Casey is far more measured, careful and accurate. Casey feels like an engineering educator first, who happens to make YouTube videos. I don’t always agree with Casey’s technical opinions, but he seems like a thoughtful guy who thinks things through.
