Based on that information, Touka has better durability than Enju. I don't know Enju's durability feats (despite watching the anime right now.) My brain is so dead. Enju should be about Tina's level who barely survives Rentaro's Vanadium fist to the gut.
With speed equal, Enju needs something that packs a punch against Touka.
I guess I'm leaning towards Touka. I could be wrong.
