Raspbee II o Conbee II. better signal?

Hi guys I hope you can help me, currently I have hassio installed in my raspeberry pi 4 model b, i want to integrate zigbee devices, i would to go with phoscon way, so I am going to purshace conbee II raspbee II but i want to know about your experience. I would prefer raspbee over conbee since i am raspberry pi i would like to have mi intallation clean as possible, I think to have inside the case is visuallly good since i won’t even see it. but i am concern about some people telling about conbee II should be installed with an extension usb cable to avoid interference issues, so does raspbee II have interference issues for you? according with the official page both have the same signal range but is someone better according your experience?

I am not using wifi in my raspberry pi by the way, and also i have philips hue bulbs in all the rooms of my house
