what is difference between home run and switch fan-out?

in designing the wiring runs of a comptuer network, what is the difference between pulling home runs from the main network switch to individual desktops 200 feet away, versus pulling 1 cable 200 feet, plug that into a small switch, and then plug 5 computers into that?

Do you need to worry about bandwidth congestion, data collision?

It seems easier and cheaper to use the second switch as a fan-out point…
