Health insurance portability

Chennai makkale vanakkam, would love to have your recommendations. Currently we have star health insurance policy, as we are hearing negative feedback about SH and also recently they doubled their premium as one of us nearing 50yrs of age.( That’s what SH gave us the reason for doubling premium). Which’s best health insurance ( cashless,wide network of hospitals and easy claim) should I portability? Thanks in advance 🙏.
