Pravin,
Since you are intending to go for self-study and contemplating books of 3 authors, my personal view is:
Padhuka - It may not suit someone who is interested in understanding the concept as it is in Q & A format. The structuring of concepts leads to confusion sometimes to connect and may lead you to lose track.
Bangar - It is too much data put in a congested way and it is not that well-structured unlike an IDT book. Its fonts and paraphrasing is not eloquent.
Manoharan - It is a good book written with concise and free flowing concept. However, the main drawback is the summary is not substantive and you may find it difficult during the time of revision especially if you do not have own your Notes.
However, if you have time and patience Vinod Gupta is the best book for self- study as it contains all the core ingredient of Conceptual clarity, Summary series, Amendment series etc.
Take a best call that suits your way of studying.
Best of Luck
Sathish
