The CalDigit TS4 is the dock to buy if you want one box that will handle nearly anything you plug into it for years. It offers 18 ports, including two downstream Thunderbolt 4 ports, three 10Gb/s USB-C ports, five 10Gb/s USB-A ports, a DisplayPort 1.4 output, UHS-II SD and microSD readers, front and rear audio jacks and 2.5 Gigabit Ethernet. Few docks match that combination of quantity and speed.
Charging is generous at up to 98W through the host connection, enough for most large laptops under heavy load. Display support depends on your computer: CalDigit lists dual 6K at 60Hz on Apple M-series Pro and Max chips, dual 4K at 60Hz on Intel Macs and Windows, and a single 8K option on supported Windows machines. Base M1 Macs are limited to one external display, which is a laptop restriction rather than a dock flaw. It can stand vertically or lie flat, and it ships with a 0.8-meter Thunderbolt 4 cable.
The negatives are cost and the fact that the extra Thunderbolt features only shine on Thunderbolt or USB4 laptops. The 2.5GbE port, for example, requires a Thunderbolt host. The two-year warranty is also shorter than Kensington's. If you just need a few ports and one monitor, a cheaper USB-C dock will do.
