Both the books won't help you much for neet. They are kind of theory books which will help you score good enough in MH boards but won't help you at all in NEET honestly and frankly speaking. Get yourself clear what you want to achieve. If you want to be a part of MBBS BDS BAMS BHMS etc programs you need to shift your attention more towards MCQ books like MTG NEET CHAMPION, HC VERMA, PRADEEP, etc. And if you are ok with scoring good marks in boards, then any of the master key or target will work. But remember, boards marks will only help you get admission in BSc courses in medical field. So choose wisely and be smart. If you have any query feel free to ask in the comments.

Best wishes. Thank you.
