What are the advantages of using AWS nameservers as opposed to servers provided by other registrars?

I am transfering a domain name from namecheap to aws route 53 service. AWS provides you with three options when transfering:

  1. Continue to use the name servers provided by the current registrar or
    DNS service.
  2. Import name servers from a Route 53 hosted zone that has
    the same name as the domain.
  3. Specify new name servers to replace the
    current registrar’s name servers (not recommended)

what is the advantage of using option 2 over the others. What is the difference in pros and cons between the options?
