LLBLGen is a far more stable and mature ORM than EF4, plus it is extremely easy to use. You simply design your database (or use one that's already designed), and you're up and running. We started using it 6 years ago, and even with the old version we were up and running in literally 30 minutes.
In general, OpenAccess is more mature solution than EF (OA's roots, like NHibernate, trace back to Java) and with 3 major releases per year, it's constantly adding more features and database support. Today, OA supports a litany of popular databases, including SQL Server, Oracle, MySql, and SQLite, and it offers innovative features like the new Round Trip Mapping (forward or reverse map at any time).
Also, don't miss the fact that there is a FREE version of OpenAccess that can be used without restrictions on any free database (like SQL Express):

LLBLGen 是一个比 EF4 更加稳定和成熟的 ORM,而且非常易于使用。您只需设计数据库(或使用已经设计的数据库),然后就可以启动并运行。我们从 6 年前开始使用它,即使使用旧版本,我们也能在 30 分钟内启动并运行。

显然,您可能会认为这些信息有偏见,因此您可以在其他 StackOverflow 线程上找到其他非 Telerik 意见:

比较和对比 NHibernate 和 Telerik 的 OpenAccess
一般来说,OpenAccess 是比 EF 更成熟的解决方案(OA 的根源,如 NHibernate,可以追溯到 Java),并且每年发布 3 个主要版本,不断添加更多功能和数据库支持。如今,OA 支持一系列流行的数据库,包括 SQL Server、Oracle、MySql 和 SQLite,并提供创新功能,如新的往返映射(随时向前或向后映射)。
另外,不要错过 OpenAccess 的免费版本,可以在任何免费数据库(如 SQL Express)上不受限制地使用:

There is a complete comparison of Telerik OpenAccess ORM to Entity Framework 4 on the Telerik website.
Clearly, you're likely to treat that information as biased, so you can find other non-Telerik opinions on other StackOverflow threads:
