I think that you might like Vernon/Rockville more than either Manchester or Willimantic. It's located at a distance in between the others and is located off of I-84.
The Buckland Hills Mall in Manchester is just down I-84 as is Hartford, and this is opposed to having to commute the more rural route I-384 between Manchester's backside & UConn. Manchester might not be as quiet as Vernon, and Willimantic offers the worst accessibility to Hartford, and almost any other location except UConn.
From Vernon, you can easily commute back to the Storrs area for nightlife options too.
When a person must choose whether to live in Willimantic, Manchester, Vernon/Rockville or out in the sticks, it all boils down to personal preference and the individual housing situation.
