I have a brand new tin of AA express that are very different in appearance to a brand new tin of JSB express.
The JSB are much brighter in appearance and the AA much duller.
I've chronoed and shot both through the same springer in the last week and got very different results.
I've also tried an old tin of AA which give the same results as the newer tin.

The last 2 batches I've had of JSB express have been consistently good

So, my experience is that they are different or that the performance and accuracy certainly is.
