Best cable clips for cat6 cabling?

I need to run some cat6 cable and I'm wondering what are the best/easiest to work with cable clips to secure them to a wall or baseboard? I see the RG6 as the most common but isn't that for coax which is much thicker than cat6?

I like these for coax, should work fine for Cat 5/Cat 6 also:
