Judging from the meat quality of these three animals, frogs are the best, because frogs generally only eat insects and the like, while bullfrogs are generally farmed in the market, and most of them grow up eating feed. Frogs are also better than bullfrogs and frogs in terms of living environment. In addition, they need more exercise than bullfrogs and frogs when hunting, so frogs have the best meat quality.
The above is purely a personal opinion, and it must be accurate for your reference only. .
