I’ll be connecting all of my Time Machine drives to the Aukey 10 Port hub, along with a USB eLicenser and my Logitech webcam. Those being the things I’m not worried about having slower I/O speeds. Even though I’ll still see a bit of an improvement from what I’m seeing on the 2015 MBP.
the Belkin Dock will have my main Media Server Drive, my Channels/DVR Drive, one Thunderbolt Time Machine drive, my Dell monitor (via DisplayPort), my Logitech 2.1 Speakers, wired Ethernet, and then a lightning port cable when I need to plug in my iPhone.
