Never had the old version, but the new one is kinda' messy and hard to peel. DH didn't like them, but once I fought through peeling the sticky-sauced shells, I thought the shrimp were tasty.
Truthfully, dealing with the sticky sauce probably results in fewer consumed shrimp. I know DH and I love grilled/skewered shrimp and would likely have eaten a lot more than we did the shrimp dish.
