Hello kannamathareddy,

It depends totally on you,

Dual Degree is better for students who want to pursue PHD, there's a better chance of getting selected in PHD for dual degree students in abroad also, and you have to spend 1 less year, but the problem is MS is pretty much useless in industrial perspective.

While BTech 4-year course is completely preferable for students who want job in industries, and you get almost same level of salary as dual program with minor variations.

I hope it helps,

Best of luck.
