Best Sample Question Paper?

I was looking forward to purchasing some SQPs for preparation. I have come across two brands which I trust the most , these are oswaal and PW. Basically, i am a student of the udaan batch and also the user of oswaal QB (question bank). My main goal is to improve my answer writing skills in sst and biology as well as time management. I am thinking of going with PW by getting the latest SQPs for science, sst , maths and previous year's SQP book for english and hindi. I am getting these 5 books for about 1k. On the other hand , oswaal is offering only those three main subjects books for about ₹1300. Can you guys tell me with whom I should go?
