Red dragon is a common species in lobster. Shrimp meat is slightly red, and the taste is much worse than that of Bioron and Hualong. 1, less meat, 2, average taste.
Hualong is small, full of shells, not delicious, and the price is not cheap.
Boston (gallon) is cheap and flashy (meaning beautiful but unreal)
Note: It is best to eat lobster sashimi (that is, raw) in restaurants, otherwise many restaurants use dead lobsters.
