I'd say go with the Immo because the other one looks pretty average to me. At least you have Immo which gives you a slight advantage. Plus the brute is already ranked :)

dont know why you "have to" choose one to focus on.... since each brute can only fight few times a day, you can easily use both. But if i d to choose, id pick the one with the bear...
