Hey aspirant, B.arch and B.tech are two really different subjects dealing with really different aspects.

If you have an interest in engineering drawing and architecture than you should opt for B.arch but if you are a technology-loving guy with an interest in the technical field and also are willing to put a lot of efforts then you should opt for B.tech.

Both the degrees have their own importance and placement is not a criterion for judging.

You should make your mind clear about which field you wanna go with and also you can choose from other fields, these two are not the only options you have.

Hope this helps.

For further doubts please ask in comments.
