You still wouldn't want to level it until it's Rare, though. As someone else pointed out on this board, leveling pets of lesser rarities can be a true chore.
As to the OP's question, there is no list because there is no "top Battle Pet". Generally all Battle Pets of equal level and rarity are comparable in power; simply select the pet with the appearance, typing, and abilities you prefer. The Battle Pets system is extremely simplistic in its implementation, and as a result the challenge becomes identifying combos you enjoy and work well. You do not have to identify specific pets that are superior to their fellows like in Pokemon, because such a dynamic is not present.
