I think your prints look poor compared with the results I get on an X1C.
To try diagnose the cause, and improve the quality, here’s a link to a simple approach that I proposed to try help someone else: Sudden PETG issues troubleshooting - #15 by CanDo
Use standard BL PLA and an external spool that doesn’t drag, and print the test block with standard settings. It’s a quick, cheap way to iterate until the block is perfect. Then you can try other filaments, nozzles and settings.
Perhaps this will help.
