Cardinal Crimson Promotion is the result of Issei choosing a different path from the Juggernaut Drive and uses his Evil Piece. I think that this form is still a bit unstable.

Empireo Purgatory Drive is due to Vali sealing the consciousness of the past possessors.

And the Supreme Silver Card is due to Kazuki mastering the Juggernaut Drive.

I think that when compared to both of theirs, his Supreme Silver Card would be stronger than the Cardinal Crimson Promotion while being on par with Empireo Purgatory Drive yet be a bit more manageable. (At least at the point of their forms introduction).
