Best Study Notes ? Schweser or Stalla ? buying, friends, noticed, package

JustasS

I am on my third book for the Level I exam and I was told by many of my friends having a good study notes will be crucial for the exam. I noticed most people either use Schweser or Stalla but I am not sure which one is better. Can someone give me some input on these ? Also what type of package should I be looking into buying? Thank you very much
