but is there any campaign originally created from users or fans that are good ?

Depends on your definition of good. There are at least three user-created campaigns.

There's this one that strings existing missions together into a mini-campaign.

I may have another campaign in the works that is only custom content that I may or may not be trying to finish during the holiday break that may or may not include Imperial heroes.

There are also a couple of fanmade campaigns in the works, as @Tvboy mentioned. He has one, @IanSolo_FFG & I have another, and one or two people on this forum alone are working on things.
