Currently CalDigits TS3 Lite works well, we have a couple, but we want to Rollout the full TS3 as soon as they become available so we can ditch the chargers aswell.

I have a Dell XPS 15 9560 with the TB16 dock. I had tried a couple (Kensington, etc), and had issues (like, buried waaaaay down in the Kensington fine print was the fact that if you had a 4K display, the USB3 ports would "downshift" to USB2, and the GigE port would go to 100mbps...)

The TB16 dock is great though, works seamlessly and smoothly with 4K displays, GigE, supports Power Delivery and remote 'wake' (there's a power button on the dock that if the laptop is sleeping will wake it).
