Unlike The Hartford AARP, Nationwide only actually operates in 46 states. However, Nationwide does offer a great variety of coverage and customer benefits. This allows you to tailor your coverage to suit your needs and Nationwide provides annual policy check ups to ensure you continue to have adequate coverage.
The Hartford AARP is more of a specialist insurer, offering coverage for members, with exclusive benefits such as lifetime car repair assurance that are tailored towards the over 50s.
So, unless you are under 50 and have concerns about your coverage level, The Hartford AARP is likely to be a better choice.
