I found Nomi's arc to be the more interesting of the two. Granted, we don't get any real action until the end, but what made it more interesting was it was more moving. It wasn't what the typical "individual seeking out a teacher to learn the ways of the Jedi" plot. We had a woman who watched her husband get murdered before her eyes. Her world was torn apart, and now she has to pick up the pieces while at the same time beginning to play the role of a single parent for her daughter. When she arrived on Ambria, she started to put the pieces together, but she wanted to cling to a huge part of her old self - the one that was reluctant to hold a lightsaber and fight others. Then again, part of her reluctance could be attributed to the traumatic experience she had when she killed her husband's killers. I know that there was an argument over whether it was justice or revenge, but as Nawara Ven once told Corran Horn in Rogue Squadron, it was one of those instances where the distinction between the two blurs.
