Go for OP Tandon if you want your concepts cleared. I personally have read the book(but not much). Apart from this, don’t ever make the mistake of avoiding NCERT, I repeat never(particularly for organic + inorganic)!!
Also I personally liked the fluid language and elaborate explanation of Chhaya Prakashani 11 & 12 chemistry textbooks. You can also go with NEET Preparatory series(Arihant) by R.K Gupta for chemistry. This book will give you a deeper insight and it’s tricky mcqs will be a boon for your upcoming NEET exam.
