Which is better Schweser vol 1 or vol 2?

I am focusing more on CFA mocks but I think I will have time for one Schweser book which is better?

I’m finding the Schweser am mocks to be less and less useful. Just took one and there was not a single mention of any currency exchange rates but 4 IPS questions. Big time tracking error in representing the real thing. That said - I did 7 AM and 3 PM from Schweser. I’d say so far book 1 is better. But old CFAI exams are the way to go for sure. I see the big difference now

From what I gather the pm mocks in volume 2 are a killer
