The Confederate Constitution hardly differed from the US Constitution as it then was on the issue of slavery. The vast majority of the Confederate Constitution was simply carried over from the US Constitution. Where it differed significantly was in more clearly protecting state's rights/limiting the power of the central government and in limiting the ability of the central government to spend money.
Have you not read the Confederate constitution?

Hardly the case but let's stick with how the two documents dealt with slavery. Slavery is not mentioned at all in the U. S. Constitution. It's mentioned ten times in the Confederate Constitution. The Confederate Constitution specifically protected slave imports, prohibited any laws impairing the right of slave ownership, prevented the possibility of any non-slave state, required all territories acquired permit slavery, and basically made it impossible to amend the Constitution to end slavery. All clauses the U.S. Constitution didn't have, and most of which it still wouldn't have had even if the Corwin Amendment had been ratified.
