There is no comparison at the moment. There are no important features missing in V2, but some might still change in implementation and there is no config tool. But you can also say V2 is already able to do things better and even some not possible in V1 due to the modular concept. The man problem is that not all hardware is supported at the moment but since I develop on RADDS or similar boards that hardware is working good. More will come soon now that the essential functions are working. So all printer systems work, autoleveing, graphic displays (128x64 pixel), normal stepper driver, endstops, temperature, laser, cnc.
