Although the storylines are different but both of the dramas have some similarities. Since it is about law, and the roles might be a little different (lawyer vs prosecutor) they both fight cases to win and they never lose a case.
In Suits, a main weakness is the PHS is a fake lawyer while in Witch's Court, JRW does anything such as use of personal attacks, fabricating evidence, or inciting perjury in order to win her case.
