LW have a hard learning curve in comparison with carrara, but for me is the best modeler with modo (that is nearly similar). Both have the power of a script language, so there are some incredible tools available for free. When we wait 3 years to have a fillet tool in carrara, with LW or Modo, just wait some weeks and probably someone will create it. BTW also without scripts the LW modeler is one of the best on the market, also for the GUI that is very efficent. Some things work better with carrara 6 pro (symmetry for example that is perfect)...
