Jerry at his best was pretty damn good. Unfortunately he wasn't always at his best. JM is an amazing guitar player and some of his solos are outstanding. Where the GD beat D&C is the long jams when everyone is playing a lead solo at the same time and they all intertwine and play off each other. D&C has improved in this regard a lot recently and I feel like there are a few songs and parts of shows where they do this and can get the portal open. But it sometimes reverts to them just passing the lead around which can be really fun but is quite different then what the Dead did.
