Thank you for your interest in Telerik OpenAccess ORM.
From the Telerik perspective our list of features
highlights our strengths, usually weaknesses of other ORM products. That comes beside the integration with the other Telerik products and the low cost considering it as part of the Telerik Premium Collection.
We recommend to take your time to prototype your use cases with 1-3 tools to find out, which product fits best and if it is well supported by communities and the vendor.
