Questions banks with or without anki in clinical years (European med school)

I'm currently in clinical years. I live in Europe and we don't have an equivalent to step 2. During my clinical years I essentially have no exams and can just skate by reading up on my patients. I don't find this enough and want to self study.

I always was a massive fan of doing questions banks, it's active learning and is actually fun. I usually put the literal question in Anki to make it stick. I also make my own cards from the question banks about concepts I didn't understand.

Now my questions. I have no interest in being a physician in America, nor do I wanna take the step exams. I purely want to do my own studying. Which question banks should I use for my goals? Uworld or AMBOSS? Again, I have no interesting in passing the steps, so my goal is purely to learn as much as possible.

Also, should I do the step 2 anking deck, or would that not be useful if I don't wanna do the step exams?
