On cashless hospital network — the most practically important figure for health insurance — Tata AIG lists 9,800 hospitals versus 9,300 for the other. That is roughly 5% more network coverage, which matters most outside metro cities where network density thins out fastest. If you live in a tier-2 or smaller town, the larger network usually outweighs a small premium difference; in metros the gap is less practically significant.

How to actually choose between Tata AIG and Chola MS in India: the insurer choice is one input, but the specific plan you pick within that insurer matters more. Two flagships from different insurers are usually closer to each other than a flagship and a budget plan from the same insurer. Use the insurer-level comparison above to set your priors (which company you trust on claim record, network, and tenure), then click into the specific plans listed on each insurer's profile to compare features, exclusions, and waiting periods at the product level. When all else is comparable, weight the insurer with the stronger published claim record — the policy is only worth what the insurer actually pays.
