The Anker 555 USB-C 8-in-1 Hub offers significant upgrades over cheaper alternatives with its 4K60Hz HDMI output, full 10Gbps USB speeds across all ports, and dual card readers. Blogged Off reviewer noted it's bulkier than older hubs but provides better heat dissipation and reliable performance. Fstoppers reviewer praised its compact size and pass-through charging capabilities, though both reviewers mentioned the lack of rubber feet and awkward dangling design.

The CalDigit TS4 Thunderbolt Dock earns its reputation as the gold standard for Thunderbolt docks, according to TechRadar's Collin Probst who gave it a full 5-star review. The dock offers 18 ports including 4 Thunderbolt 4 connections, 98W power delivery, and exceptional build quality that feels durable and reliable. The Verge's Dan Seifert praised it as 'nearly perfect' with the most well-equipped configuration available, though he noted the $380 price tag as a significant drawback.

How they stack up

Anker 555 8-in-1 USB-C Dock

The Anker 555 excels in 4K60Hz HDMI output and full 10Gbps USB speeds, surpassing the UGREEN Revodok Pro and HyperDrive 12 in display and data transfer capabilities. However, it lacks Thunderbolt support and is bulkier than the Satechi 15-in-1, which offers wireless charging and vertical device organization. Compared to the Dell D6000, it's more affordable but doesn't support triple 4K displays without DisplayLink drivers.

CalDigit TS4 Thunderbolt Dock

The CalDigit TS4 Thunderbolt Dock stands out with its 4 Thunderbolt 4 ports and 98W power delivery, making it superior to the Anker 555 and UGREEN Revodok Pro for high-performance connectivity. Unlike the HyperDrive 12, it offers true Thunderbolt speeds and better build quality, though it's significantly more expensive than the Dell D6000 and Satechi 15-in-1. Its bulkiness and premium price make it less appealing compared to the more compact and affordable alternatives.
