Personally I like the Schweser notes. But this is coming coming from someone who is just out of school and has been exposed to 95% of the information in the level one LOS. I talked to one of my professors, who used to be a big Chicago trader and CFA instructor up there, and he agreed that the Schweser notes are a great tool for passing the level one exam.
The problem stems from what I would call when such materials create a "paper" CFA. I use this term as it was widely used in the Microsoft certifications, as many candidates could pass the exams using sample exams and shortened notes, but were not worth a thing when it came to doing the actual job.
To make this short: If you have been exposed to the material before, get the Schweser notes and hopefully find a buddy who has the text to reference for deeper understanding. Worst case scenario, you can usually Google a topic and get a plethora of information. If you are relatively new to finance and haven't attended a large variety of college level finance courses, I would recommend getting *both*, but in the least you are going to want to read the books. The "extra" material found in the books really helps nail the material down in terms of being able to analyze it as opposed to simply memorizing it. That extra understanding is going to be worth more to you in the long run when it comes to an interview or opportunity to display your skills.
