We would recommend you OpenAccess over Nolics for a number of reasons:
- Ease of use
- The future versions (4.0 will be the first one) will use OpenAccess. An unified ORM for your CMS and custom modules will be great.
- Much better documentation.
We know some cases in which people have succeeded with SubSonic. Of course if could be a personal preference, but we have chosen OpenAccess for our official ORM.
All the best,
the Telerik team
