With force enhancement(speed, strength, and agility), Shii-cho can be formidable to users of all other forms. Kit Fisto gave Ventress a good fight before she eventually defeated him, and he bested General Grievous (only leaving when a group of magna guards joined in), both form 2 users. In the ROTS novel, he also put up a good fight against Palpatine. In fact, he was still going when Anikin showed up.
