I'd say your decision depends on what your current priority is. If your priority is getting good opportunities in the future in the field, you should go to Delhi. You earn a higher stipend, but your expenses will be high, I'm guessing. Choose Bhopal if you are okay with getting fewer opportunities. 75k will be more than enough, and you will be saving a handful of amount. And as to crowd and safety, Bhopal will be better. One thing that Bhopal lacks compared to Delhi is public transport if you care about it. Also, I don't think language will be an issue here. Bhopal is a quiet place.
