Fatalities are something untouched in both last blades, unless you are counting the cutting them in half that both Last Blade arcade and Samurai Shodown allow. But as for Desperation and Super desperation moves, I would say Last Blade 2. Juzoh and Shigen's branching super moves are very cool, and Setsuna's 2 part SDM is cool. The first part, the mega lightning zap, does damage up close, and allows you to combo the electrical punch, uncomboable otherwise. And the second part is on of the coolest SDMs I have ever seen.
