Is RMC-1 2x times better than XMC-1? Please share your experience

First batch of RMC-1’s is delivered and few of them have already listed for resale. Any owner of these unit please share your first impression of how RMC-1 performed in comparison with XMC-1, as well as Theta Digital Casablanca. I have experienced XMC-1 and considering either the RMC-1 or Casablanca for the next upgrade.
