Buying Liability Insurance

As a new grad starting my first job, I am in the market to buy liability insurance. I've done some initial research on liability insurance offered by NSO and Proliability through ANA. Both offer new grad discounts, I'm sure hoping to get my business for life, and both coverages seem very similar. Does anyone have feedback on this issue?
Thanks!

Both providers (NSO and Proliability) are reputable and have been offering nursing liability insurance policies for many years. NSO is the more widely-known company of the two, but I think you'd be safe with one or the other.
