You need two independent timer channels and you're sick of running separate power rails for each. The NE556 puts two complete 555 timers in one 14-pin package and shares the power-supply pins between them. One chip, two channels, half the wiring. Whether it's a multi-stage delay circuit or dual oscillators driving different loads, this is the clean way to do it. Solder it in once, route your signals, and stop fighting your breadboard layout
