It depends upon a lot of factors like your profile, career goals,your budgets and other several factors. But if i have to give a generalised answer:-

When compared to other B schools in India, doing an MBA from CEG may not seem like a good idea beacause CEG has its reputation mainly for engineering. But it has a good brand name which can add weightage to your resume. And considering it's fee structure it is not that expensive too.

Now talking about DOMS, it has a good brand name so good companies will be visiting your campus. The return on investment is also good. The batch size is small too.

However, if you have offers from other B schools do consider them too. If you want a job, MBA from CEG or DoMS is not a bad choice. But if you want a succesful career in this field try for other reputed B schools.
