Bojutsu Kung Jin if you're looking for simple, or you can also go for Reptile, the new patch made him much better. Outlaw Erron Black is very good, just gotta get that punch rush string consistent and you're pretty much golden.
Then you got your more "difficult: characters, mostly run cancel ones, so if you're ok with that you can go with Jax, Johnny, D'Vorah (Swarm Queen) and Cassie (Hollywood mainly, but her others are good too).
Then you got ones like Tanya (Kobu Jutsu), Ermac (Master of Souls) who's more of a 50/50 but he's still pretty rushdown, at least imo. Kung Lao (Tempest or Buzz Saw), Sonya (Covert Ops) and Raiden (Thunder God).
Most of these characters are "rushdown", some pressure, others are 50/50's, it's up to you really what you want to go for.
