I can't comment spesifically on the wines and vintage. But both are the top Aglianico del Vulture-selections from d'Angelo. They come from different vineyards. The valle del Noce is a quite new selection. The Caselle has been around for years. Both are traditionally made and normally the Valle del Noce has a little lower yield and is a little more expensive. 10$ seems quite a huge difference. I thought they normally were closer in price. So that votes for the Caselle.

If they go cheap I would surely be interested to try both. These are often very good wines for the price.
