Hello,
It is a good question from student's point of view.(#) Degree programme: These are much high valued then Diploma. Degree like B.Arch provides profundity about an architect course than Diploma. It has more opportunities as compared to Diploma. Degree is being issued through recognized university or college. The duration of obtaining the degree of architect is greater than the duration of Diploma.
(#) Diploma programme: Like Diploma in Designing, planning, architect etc. are a Diploma course. The admission to Diploma course can be taken after clearing high school examination (class 10th). An institute, a Polytechnic, or even a university can offer a Diploma course. There is no need for the institute or the university to be UGC or AICTE approved. Both programs /courses have their own utility and valuation. But, I would suggest you to degree course, since it is approved and certified by the institution. But, if you want your career to be more accelerated, then along with the degree course, you can pursue Diploma course.
