Nitin, this is an overly wide question, to be honest; the answers are going to be all over the place probably. Both mirrorless and DSLRs have their specific pros and cons. And part is personal preference too, some people will lean one way, some the other. Same goes for brands. And ultimately, all those personal preferences will teach you little, as they may not apply to your situation at all.
So, if you want useful answers for your situation: what kind of photography do you do most, what specific features are you looking for in a camera, have you tried any of these cameras in a shop to see how they fit your idea of how a camera should work, and how they fit your hands, and most of all: how much can you spend?
