As a level 76 soceror, I dont equip either. Chimera looks cooler and is a harder pet to earn for balance. But the cards these two pets give aren't the best in my opinion for a balance wizard companion.
The best balance pet companions give a blade or heal spell of some kind. I recommend the beast that compliments your best secondary school spell (example the fire one if you like to use helephant or fireball)...Or go with a pet that has Dragonblade card (like Ianthine Hound, Polar Cat, Alert Hound to name a few).
For pets that give a healing card, go with Samoorai, Defender Pig, or Firewalker (looks like a burning tree). They all have a healing card.
One last pet to consider, the Hollow knight has a great shield card that gives +185 defense per pip. If you equip ice mastery amulet and have full power pips, you can really stay in a fight a long time 7x185=1295 defense, but for power pips 7pp x 185=2590 defense. I'd consider having one of those very highly as a balance wizard...and he is a Must for an ice wizard pet.
Which pet should i equip. Judgement or Chimera?I have hardly trained my judge What should i equip?

Chimera has selfish talents train your Judge but if you want a awesome pet get the sea dragon or deer knight that just came out. Deer knight because it has a couple of free spaces for talents. Sea dragon because its really good but harder to buy.
