Rancilio no longer lists the Rocky (its page now returns 404) and sells the Stile as its home grinder, so you'd be buying the Rocky used.

The same number means different things
Both grinders use a numbered dial, which makes it tempting to copy a number straight across. Setting 9 sits at grind index 7.5 on the Rocky but 35 on the Faustino — far enough apart to change the cup.
Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.
Rancilio Rocky
Rocket Faustino
Dialing in the Rocky
A stepped espresso grinder that has been the budget recommendation for a very long time. The 55 steps across 50mm flat burrs are its limitation — for espresso you will sometimes want a setting between two of them and there is not one, and a single step can move a shot by seconds. Twenty of those steps cover espresso through filter, which is more resolution than the fine end usually gets at this price. Two things make it an espresso grinder in practice rather than a general one: changing setting means holding the locking lever while twisting the hopper, and it keeps a couple of grams in the chute, so every switch between espresso and pour over costs you both fiddling and coffee. Most owners pick one end and stay there.
Dialing in the Faustino
Rocket's grinder, built to sit alongside their espresso machines and tuned accordingly. Stepless, espresso-first, and best judged on how finely it lets you creep toward a target shot time rather than on its coarse range.
