Stalla - Level III

Did anyone use/pass with Stalla. I used Stall for Level 1 and Level 2 and passed both years, but most of the posters here seemed to use Schweser. I briefly used Schweser as I attended the Windsor SSFA for Level II and found the material was covered very similar for Level II, perhaps Stalla goes into more detail on the concepts. Any feedback would be great, I plan on reading the CFAI textbooks for the first time for Level III and probably attending Windsor again as I was told by attendees there that there is good value for the morning session of the exam. Stalla or Schweser?

I found another thread on this question already asked…thanks for the feedback.
