My father purchased this insurance for me a long time ago, it was previously known as apollo munich health insurance.Seriously!! are they better then others ?
2 years before I researched this on ditto to change for better alternatives but didn't find any. I think HDFC Ergo is one of the best.
I have optima restore but you may check optima secure.
I know Optima restore provides Pre And Post Hospitalisation (All your pre-hospital admission expenses up to 60 days, and post-discharge expenses till 180 days are included.)
Additionally, you can compare plans here on ditto as well: https://joinditto.in/health-insurance/compare-plans/
I was hospitalized for 9 days and took a private room. The bill was around 1.2L and they reimbursed around 1.17L as some things (don't remember now) don't fall under the criteria for reimbursement.
