Both options can charge and pass data through a single USB-C cable, which is awesome.
These monitors act as hubs were you can plug a bunch of stuff and they’ll be readily available when you plug in your Mac.
I have a 27 inch 4K Dell (U2720Q). I use a 7-port powered USB hub, with a bunch of peripherals attached: scanner, keyboard, mouse, charger.
Works like a charm.
The new Dell models even include a Ethernet port, have very thin bezels and no ugly logo on the monitor.
