Which is the best in Mediclaim Insurance?

I have taken Royal sundaram Mediclaim policy last year. Premium 1,745 for 1Lac. I have to renew the same for the 2nd year before 4th Apirl . what i feel is 1,745 premium is too highfor 1Lac. Now i want to switch over to other mediclaim insurance except Royal Sundaram & ICICI Lombard. Please Suggest me the very best one .
