As per the information available online, I would arrange them in the following order(here the course structure and the greater possibility of getting a job is considered):

1. Btech Biotechnology in srm University
2. bsc+MSc biotechnology in VIT
3. btech biotechnology in sathyabma University
4. BSc Biotechnology in Amrita University
5. bsc biotechnology in manipal University

If you are aspiring to do job after your bachelors then go for BTech courses and if you aspire to go for research or advanced studies then I would say BS-MS is more preferable. If you want to study MS from different institute then you can go for BS.

** This is based on observations and information available. Before taking decision you should personally check all the colleges and decide remembering the facts provided.

I hope this answer helps. All the very best for your future endeavors!
