Subsonic ORM experience

Question

I\'m looking for new ORM for a important project, im used to nHibernate with ActiveRecord and I already have a very bad experiencia with EF4, performance and crashing GUI.

Answer 1

I used Supersonic, it's good as long as you are using simple queries. When I started to have more complex queries I saw that it lacks LINQ features. After googling a little I switched to http://bltoolkit.net, and from that time (about 2 years now) I'm very happy with it. Plus is one of the fastest ORM as per http://ormeter.net/. Take a look it, you won't be sorry.
