FinQuiz Notes vs. CFAI Books only, previous, stories, whether

Wendy01

Anyone use FinQuiz notes solely to cover the curriculum, only adding EOC ?’s from the CFAI books?  Most people swear by Schweser (having stories of never opening the CFAI curriculum for any of the three levels) - wonder if the same is true for FinQuiz Notes?  First time user of FinQuiz notes so wanted opinions of previous users to see if those notes are enough or whether I still need coverage using Schweser?  Thanks.
