You really shouldn't use the anime to compare things. The anime is usually trolling; in GO, Fire Tornado DD broke through King Fire. In the game, I highly doubt Zanou can stop Bushin Renzan without a hissatsu.

With that said, I vote for Soul Bringer. It's one of the strongest solo Keshin shots and is used by the strongest solo Keshin in the first GO game.
