I would like to understand how is this IC better than an RC?
My objective is that, I would to generate a power sequence for a device.
In that case, I have an option to use this IC or use an RC (with the right time constant).
In that case, how is this IC more advantangeous than a simple RC? Or is the RC a better choice?
It monitors the absolute supply voltage rather than following whatever is there.
It gives a more precise delay before releasing the reset.
It gives a logic change output rather than analog.
It debounces the manual reset input.
It takes up less board space!
The more elements there are to sequence, the better a
purpose-made sequencer looks. When sequencing involves
any logic at all, forget the discrete cobble.
of course one would at first think about a Power On Reset...
But the OP asked for power sequencing a device .... without any further description. (So we know it is NOT used as a POR)
While a RESET input of a microcontroller has specified levels usually including some hysteresis ... we don`t know nothing about the power sequencing circuit.

It´s like asking about "nuts and bolts" (RC) to be used in a "gear box" (power sequencing) but not saying anything about whether the gear box is in a car, bicycle, a kitchen machine (size, force, or any other specification | function, timing, accuracy..)
