Overall Conadria has performed better for me in NH. Generally more productive , earlier , and reliable for me , and slightly more forgiving with harvesting a little early.
My Atreano , more than any other variety I've ever had , required being absolutely dead ripe to bring out its true flavor , as if the infusion of flavor only happened in the very last few hours of ripening.
My Atreano was the RR strain as far as I was able to determine. When dead ripe it was very good.
