Materialise Vs. Netfabb - better nesting capabilities ?

Hello everyone.

My name is Gilles and I work for a service bureau that has recently purchased a 3D metal printer.
Up till few weeks ago, we used to work the old fashioned way using molds and other stuff. Today, as 3d printing has become increasingly popular, we decided to move forward with technolgy. I am in charge of the whole 3D thing in my company - updating our old working methods and adapting them to the new era of 3d printer, indoctrinating other employees this kind of knowledge and most importantly - purchasing the necessary and the most efficient softwares.

Since we mass-produce and mass-print metal parts, we are trying to figure out these days which software - Netfabb or Materialsise - has a better nesting tool. This is crucial for us.

We'd be grateful to hear your feedback if you use one of the above. Please let us know both their drawbacks and their advantages.

Thank you in advance, your help is much appreciated,

Gilles.
