Elecraft KX2 or Xiegu X6100? I put both radios side by side: data from the manufacturers’ spec sheets and photos to the same scale. The Elecraft KX2 comes out ahead: second receiver, transmit current draw and weight; the Xiegu X6100: 6 m power, AM power, spectrum and waterfall, antenna tuner, LAN / remote control and SD card.
