You look immature or at an early stage of preparation to ask such a question.
Anyways, as a fellow BITSian,
Here is what I’ve to say,
BITS Pilani , Pilani Campus is better than all the other NITs and equivalent to IIIT-H and old IITs. However, in some cases people prefer IITB CSE against BITS CS and vice versa. So that’s a choice.
Overall, yes it’s as prestigious as the mighty IITs out there. And NITs? Yes all three campuses are better than the top NITs in overall parameters.
