My BITSAT score is 305. I may get Dual degree at BITS, Pilani. Is it a good option? What are the future prospects and placement? Are Dual degree students treated at par with BE students? what is the real scenario?

I am getting all branches at NIT Rourkela. Should I prefer Dual degree from BITS, Pilani?

The future prospects and placements of dual degree are at par or even, better than BE students. They are definitely treated at par with BE students. I would suggest you to go for the same. 

CSE at Rourkela  is also a good option but still the value of a degree from BIT Pilani and their course structure is awesome. People take BE only because they don't want to study for another year.
