Dear candidate, it all depends on college from where you are pursuing and your interest. If you are pursuing integrated degree from any NIT/IIT/IIIT/BITS or any other good institute, then there is no problem. However, it is observed placements in integrated M Tech is less than B Tech and hence there admission cut off is also lower than B Tech program. If you are planning to pursue integrated degree from private college or any normal college, then you should think once more. You can pursue B Tech from such institutes and then you can give GATE, and pursue M Tech from any government college or good private college. However, it also depends on your interest. If you are pursuing integrated degree and later you realize, that you have no interest in this branch, then you will have no option to change in later stage. Integrated degree is tiring and hectic too.

Hope, it helps!
