What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
CalDigit TS4
Two whitelisted hands-on testers — The Verge and TechRadar — rate the CalDigit TS4 the best Thunderbolt 4 dock available (The Verge calls it the "king of Thunderbolt docks," TechRadar the "gold standard"), praising its 18 ports, build quality and 98W charging. Both flag the steep ~$380 price and lack of a dedicated HDMI port. The Verge scored it 8/10; TechRadar gave a full 5 stars / Editor's Choice. No RTINGS, PCMag or Notebookcheck TS4 review was included; other coverage was non-whitelisted. (2 sourced reviews, 2 lab-tested.)
Praised: Best-in-class connectivity — 18 ports spanning Thunderbolt 4, USB-C/USB-A, DisplayPort, Ethernet and SD/microSD; Sturdy metal build with reliable, plug-and-forget everyday operation; 98W laptop charging plus offline/passthrough charging of accessories when the host is unplugged.
Flagged: High price (~$380), among the most expensive Thunderbolt 4 docks; No dedicated HDMI port — video out is DisplayPort or USB-C/Thunderbolt only; Physically bulky and not very portable; The Verge notes a large 230W external power brick.
