Sauron didn't directly stay in the world because of his ring, though it may have had some part in the preservation of his power after his physical body was destroyed. His ring did not amplify him in any way when it was not on his finger. The only effect the ring has is amplifying his power when worn, and reducing it when destroyed. Also, Saruman was corrupted much later than the Balrogs, and was sent by the Valar to do a specific task. In my mind, it makes more sense that they'd recall him for judgment than them recalling Balrogs, who were corrupted long ago. Additionally, you say that the 3 Balrogs we know were killed, obviously did not go to Utumno. And whyever not?
