The ONLY thing that Noteshelf has on you guys is the writing experience. Noteshelf has true marker feeling with lights and darks as you write. The pencil is far better... goodnotes' pencil (while appreciated) is primitive in comparison. The writing experience should be a priority to pull in a whole new category of work - art. It doesn't have to be all art tools. I don't expect it to be an art app. But I would love the writing experience and sketching experience provided in Noteshelf that, in actuality, they have had for the past 10 years. Everything else about GoodNotes is better, in my opinion.
