MCA is generally assumed equivalent to B.Tech in IT and CSE field as course structure is same but B.tech provides more scope and generally B.tech candidates are preffered over MCA and higher salary is offered. 

If we compare both these courses then B.Tech is a better course as it is technical course but both the courses has its own importance and depends upon the candidate interest.

If student has interest in computer then he/she can go for MCA. 

Good luck!!
