Joe rocket high end jackets would be the low end Alpine star or Dianese jacket. that is a FACT! not even in the same universe as far as quality!
the fit, finish and supple leather of an Astar or Dianese compared to a Joe rocket is like comparing a 1980 suzuki to a 2013 suzuki. Have you bought any of the new top of the line Astar leather jackets to compare? if so, which one?
You really are off base on this one. Joe Rocket & Alpinstar are considered the Ford & Chevy of leathers. If I remember correctly they both get their leather from the same supplier and both use 1.4mm leather with triple stitching on their high end stuff. Both make cheap stuff and both make race quality stuff. I think maybe your experience could have been low end JR and high end AS?
Both do a pretty good job of crashing. From my experience both hold up better in a crash than dainese. Dainese is the most comfy leathers I have ever worn and all I use for street but I wouldn't even consider it for track use.
