Sketch bend vs Edge Flange

What is the difference in the Sketch Bend Feature and theEdge Flange feature? And when should you use one over the other.Just for some background we do alot of manufacturing of waterjetparts and then bend the parts and we have many old waterjet profilefiles.

It looks like the edge flange features has more options than thesketch bend like relief.

Thanks
