JJP build quality - still no better than Stern. Which is no better than BW was.
JJP Problems - WOZ had it's fair share of serious problems. Most seemed to be fixed now. Stern ships pins out with serious problem and sometimes fixes them.
JJP BOM - Beats the hell out of stern. JJP threw so much stuff on WOZ I doubt they made a dime on them. Probably at 9k they do. Stern continues to ship less and less and charge more.
JJP shipping - This has become a joke. They still can't ship a machine anywhere near promised times and still three month people to death. Who knows when Hobbit will ship. Stern wins.
JJP Price - The price is too high Stern has a pro still, which they charge too much for. But at least it's a budget option. Nobody wins on this.
IMO, if you want more stuff on a machine JJP beats stern hands down. If you want a new machine now, stern beats the hell out of JJP. The rest is equal in my eyes. Now, as far as fun factor? Stern hasn't delivered a great machine since ACDC. The Hobbit looks like it might be fun but I've never played it.
