The RPi 4 is the first one with an Ethernet interface that isn't connected over USB. All the earlier RPis are seriously handicapped for networking usage by that limitation.
sure, but the espressobin has a gigabit switch onboard. and that switch is controllable from Linux, and treated as a bridge device, easily manipulated from brctl.
while the rpi3 spanks the espressobin on CPU, the espressobin destroys pretty much every other dev board (including rpi4) in the price range with regard to network functionality.
