Well, all the pets are viable now for one thing or another. There are still the pets that rise to the top.
Cats are still higher DPS than wolves- but not by a game-breaking amount. Wolves just add their DPS in other ways.
Gorillas are the king of Tenacity pets at the moment, but bears are still great pets. It's like the difference between a Prot Pally and Druid tank.
Spiders are incredible PvP pets because of their 4 second pin. Other Cunning pets are great for PvP, but not as OP.
