Dear aspirant !

Hope you are doing great ! Btech undoubtedly ,has its own value . Any bsc course can't be compare with it , let's take a example two student are there , first one is who have completed his btech and second one whi has completed his bsc astrophysics , definitely first one with btech will be in advantage than second one , btech gives you more exploration and deep knowledge of that any particular thing , so btech guy will be given more preference .

Go with btech ,rest depend on you and your field of interest ,bsc is also a good course and if you are really interested in it then go for it .
