Rating: 4/5, Liked it a lot
Justin's makes a great peanut butter, and their peanut butter makes for a great peanut butter cup. The chocolate's mildly dark flavor accents its sweetness. It's not a strong dark, and Justin's high-quality peanut butter provides a salty counterpoint. I do like to peel off the chocolate from my peanut butter cups, and Justin's thicker shell doesn't peel off as easily as Reese's, but on the other hand, the peanut butter is richer and tastier than Reese's, so that's a plus.
It is worth noting that I'd give Justin's a 3/5 on value, as they tend to be a hair on the expensive side, but they're certainly delicious. With Justin's, you get what you pay for.
