Cima study Vs Astranti??

I have been researching all affordable cima materials out there and it seems to me astranti isn’t bad at all. However, I need to be sure before setting out on this new journey what kind of materials I can count on to aim at passing at the first attempt for every exam. As cima study prime fees include kaplan text books (as we know cima official ones) I thought this would be the best option, but unfortunately i found lots of other options and now I am caught up in this little dilemma that’s being an issue for me to begin. I would like to know if astranti is an appropriate alternative or cimastudy is still way better.

Can someone help me to make it to better hints, please?
