I used Stalla for L1 and L2 and passed.
For L3 I purchased Schweser. Very interesting difference.
I think Stalla has more diagrams which helps a lot with the understanding. Schweser on the other hand is almost completely written. The plus point for Schweser is that it has many more sections on tips on "how to" prepare for the exam.
Much of the L3 material is actually the same as L2, so I will be using both to prepare.
