Triple H vs. Taker; Hell in a Cell Who would win?

Hey guys, now for those of you that don't know, Triple H and The Undertaker have been known as the Kings of Hell in a Cell, however, Triple H and Taker have faced each other in the ring many times and they have also competed in the 1st ever 6 Man Hell in a Cell, but they have never faced each other 1 on 1 inside Hell in a Cell.

and so, my question to you all is this:

If these 2 were to ever face each other inside Hell in a Cell 1 on 1 whether it be Wrestlemania, Summerslam, Survivor Series or any other PPV or if it was on RAW or SD! and even if it was for the WWE Heavyweight Title or the World Heavyweight Title who would win the Hell in a Cell Match?

Triple H or The Undertaker?

THAT'S THE QUESTION!

Please let me know what you think about that.
