Elder Kais are very rare unfortunately, they should only be used on the very best cards, and SSJ3 Goku isn't one of them... :/

To answer your question, yes, SSJ4 Goku is stronger than TUR SSJ3 Goku. His stats are better, his passive skills are better, he can even dodge and counterattack super attacks... and next to SSJ4 Vegeta they both gain +35% ATK and +6 Ki, so they basically super attack every single time. And Goku's super attack greatly increases his own defense, while Vegeta's super attack greatly lowers the enemy's defense. In other words, they're great on their own, but they're unstoppable together. SSJ3 Goku just pales in comparison!
