Should i use cengage or Dc pandey in mcq preparation for NEET..?

Ideally, you should start your preparation with NCERT books. Around 95% questions in Neet are directly asked from NCERTs. You must complete NCERTs first. Once done with this, you can move on to standard reference books. Now coming to your question, DC Pandey seems a better choice for Neet compared to Cengage. Also most of the educators recommend HC Verma and DC Pandey as the best choices for Neet Physics.
