I agree - Ghirardelli dark is also very good. Hershey’s tastes ghastly by comparison, and deserves a worldwide boycott. ;)
IMHO, Ghiradelli dark chocolate is probably the best dark chocolate I’ve ever had - it melts so readily, so smooth, and so chocolatey. Lindt dark chocolate is good, but for me only up to their stuff that’s 60% cocoa. Beyond that it’s just too bitter and slow melting for my tastes.
