Obviously NPCs can never be as challenging as real players. But playing against Desan or tavion with dismemberment enabled is not that easy for noobs like me . Online battles are also nice, but in a totally different way IMO. There it's about competing, it's basically a sword fighting game with a few techniques that are like a MP gameplay paradigm. I don't want to degrade it, it's sure a lot of fun. But what makes the SP so compelling for me, is the cinematic, Star-Wars-like experience. All sorts of force powers are used, sabers are thrown, jumps made etc. It may not be the most effective fighting stance, but it feels very authentic and epic to me. Plus the mentioned fluency of SP compared to MP.
