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 16 sits at grind index 38.2 on the Barista Touch Impress (built-in) but 21.3 on the Rocky — 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.

Dialing in the Barista Touch Impress (built-in)
Built into an espresso machine and tuned for it, with the grind range weighted heavily toward the fine end. Perfectly capable within espresso; if you also brew filter you will find the coarse end short.
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.
