My Vista has always out-performed all the VdBs I have. Better grower, better fruiter.
I have a couple dozen Celestes, Celestials and Blue Celestes that all test the same by DNA, but they definitely do not all perform the same. "JN", "GM", "PM" and Blue Celeste "JN" are the winners here.
Seeing the variability in Celeste, it does not surprise me that VdBs vary as well.
