Which one should you get?

It suits a full desk with several USB devices and a wired network, and adds the most IT management features.

Its HDMI 2.1 port takes a TV or monitor without an adapter, and it is about half the weight.

Both need a USB4/Thunderbolt 4 Surface for two 4K screens; a plain USB-C Surface gets one 4K display.
