Which college is better, LD or MSU Baroda?

It depends on the course you are willing to pursue. As one of my friends is an alumni of MSU and also knows about LD, I can help you with the question. 

According to him, if you are willing to study engineering then MSU would be a better choice than LD. The overall academics and curriculum is better at MSU, whereas LD has a somewhat better reputation among industries than MSU. Therefore, placements are better in LD. 

But if you think you can secure a job offer by yourself go for MSU as they will provide you with the proper academic guidance. 

Also if location is your preference then if you are near to Vadodara go for MSU and if you are close to Ahmedabad go for LD.
