I'm very happy with the OWC dock -- it's been rock solid, and in the eGPU/Intel config allowed single cable by daisy chaining the eGPU off the dock. I had a similar experience with their ThunderBolt hub (which is just 3 TB4 outs, 1 TB4 in).
I've theorized for a while that the OWC, Razer, Belkin, and Kensington TB4 docks are all the same (Razer sacrificed a USB port for RGB) -- they have the same basic layout, and same basic capabilities. The CalDigit TS4 looks like a different design, adding some more ports.
I have a friend with various TB docks w/ Intel Mac + eGPU, and have experienced a consistent issue when using a secondary USB-C DAC for audio. I haven't, but if that's your scenario, might be worth a pause.
