I suggest just getting the Belkin and get something you know will work. It is also the cable recommended by Apple for the ATV4K, and really isn't that expensive:
I totally wanted the Belkin cable from Apple but at 6 feet its too short because I have my cables run thru my walls and needed at least 8 footers. Couldn't find the Belkin cables any longer that 6 feet...
