I used only CFAI in December for level 1 and passed. I was really stressed about not having the Schwesser or Stalla info, but it ended up working out. I focused on the EOC questions, purchased two extra sample CFAI exams and did the mock.

I'm in a better situation now financially and purchased the QBank about a month ago. It is certainly useful, but not necessary. More than anything it is a change of pace. It also provides extra questions in case you have tons of study time and feel like you are starting to memorize the EOC answers (rather than material). I don't think there is much difference in the difficulty level, even when you set the QBank to "advanced" questions only.
