Since there's obviously a family tiff, who do you believe? That's right - neither of them.
Crower VTEC cams have always been prone to breaking, they mostly fixed the problem 5+ years ago to the point where Skunk2 Pro's were a less reliable cam. Recently they released a bunch of blems - either old cams they sat on for years, or another batch of crapola - and there are a lot of cams breaking. For SOHC or LS, their stuff is quality.
Brian Crower cams are, honestly, not the biggest on the market. They are very much marketed at the streetcar crowd, and as such they are a good value. Josh's LS is the first set of Brian Crower's I have seen or heard of breaking... the fact that Josh was involved leads me to believe it was installer error, or he got a "sweet deal" on the head/motor which had different caps swapped onto it at some point.
Everyone recommending GSR/ITR for a turbo vehicle is correct.
