Guidance on Joining Decision – PwC India vs TCS

I had my last working day at LTIMindtree on the 8th, and they paid me the remaining notice period amount. They only allowed me to serve 42 days of notice instead of the full period. I currently have two offers — one from PwC India with a joining date of 4th September, and another from TCS with a joining date of 6th October. I am unsure whether I should look for better opportunities after the 4th or join PwC India. Kindly suggest.
