Hi Adesh
Out of the 3 you mentioned, Cengage is just the right difficulty level for advanced. Thomas is too difficult, and you will only end up wasting time over unnecessarily difficult questions. The theory in cengage is also very precise and to the point and can help build your concepts.

Dear,
I would recommend Sameer Bansal for Calculus,if you just want a book with problems. But, if you want to understand the concepts then cengage. Both are equally good books. If you have understood the concepts then go for Sameer Bansal else Cengage. Calculus has certainly an appreciable weightage in JEE. These books should will help you develop the skills and intuition to tackle the problems asked. All the best.
Hope this helps!
