The JAN5670's are good tubes.
Aside from the label it is very hard to tell them apart. The internals appear identical. The glass on the JAN series is perhaps 1-2mm taller than the 5 Star.
The GE 5 Star 5670 (any color) came off a slightly different line. The 5 Star line up are tubes that were specifically recommended for mission critical uses such as avionics, medical and broadcasting. Very tough, high tolerances, and easily able to deal with many on-off cycles. The quality control from inception to final product was also amazing in that better than 97% of the finished tubes made to market while only 3% made it to dumpster!
I have both and I can't tell the difference sonically at all!
