Stalla or Scheweser Q Bank for Item Set Questions

I am looking to purchase q bank from either Stalla or Scheweser. Which of them is better , I am looking specifically to practice item set questions, with vignettes and all. It looks like cost-wise Scheweser is better , but I wouldnt mind spending an extra 150 dollars if Stalla has better practice similar to the level 2 item set type questions.

go for Stalla
