Buying naked options, brokerage breakdown between MIS and Nrml in kite?

Hello guys I recently got into trading options. I was wondering what is the difference in buying mis options and Nrml options? Also what are the advantages in either of them? There is definitely no margin advantage because I am only paying the premium while buying options. Any response and answers to this will be really appreciated. Thanks in advance.

The main difference is for selling options, where the margin requirement drops to 50%.
