A simple search in google would be answering your question related to differences between both of them
Extract from Google, if you search for it

Health insurance is designed to pay for medical treatment, drugs, and preventative check-ups for you and others covered under your plan.
Life insurance provides a cash sum to your loved ones if you die during the length of the policy

If you are asking which one to prefer -then it depends on your preference between health or life.
Since both are important - it is important cover them both under insurance
If you already have health insurance covered (as a dependent from your parents coverage or a standard govt policy ) - then you can go with Life insurance. The life insurance is very important for an individual, when they are only one income earner for a family.
Note : In terms of life insurances , I personally to go with term plans rather endowment plans
