CBSE all the way.
You should be knowing that NEET is an exam held under the CBSE. Thus, the portion is pretty much what the NCERT books have in them. And trust me, you don’t want to study from a special ‘board exam textbook’ for your boards when the NEET pressure starts to sink in (this happens during the prelim exams period, when both boards & NEET come charging to us like wild horses on the loose).
So, CBSE is The Choice.
