I would definitely take the
Alvin over the
Titan.
Also something interesting I read on Wikipedia about the
Alvin:
In an emergency, if Alvin were stuck underwater with occupants inside, the outer body, or cladding, of the submersible could be released and discarded using controls inside the hull. The titanium sphere would then rise to the surface uncontrolled.

I am betting the
Titan did not have an escape system like this built into it judging by the photos of it. You would think a lifeboat type system would be mandatory on a DSV, but I guess some lessons need to be relearned.
