I used to have a conbee II connected to Zigbee2mqtt and would always have issues. Random devices would stop working, or I would need a restart. With the SLZB-06, I haven't had any issues! Another benefit is that since it Zigbee2Mqtt talks to the device over serial to TCP, I don't have to run the container as privileged to get access to the USB device. This makes my set up more secure overall. (source: https://www.amazon.com/product-reviews/B0BL6DQSB3/ref=cm_cr_arp_mb_viewopt_srt?sortBy=recent&pageNumber=4)
