Not sure about extremely young plants, but:

San Pedro (T.Pachanoi) have rounded ribs, and definite, albeit often very small, spines

Scopulicola have pointier ribs, and non-existant spines. They are also usually a duller green colour compared to a pachanoi deep green/blue.

Notice the indentations at the points where the sharp pointy bits come out on a pach and they generally point upwards whereas a scop is comparitively seamless...and my scops are heaps darker in colour than any of my varied pachs.

They are quite distinct.

I'd like to see the longer spine phenotype of scop compared in this thread but I don't know of any good pictures of it.

Indeed, when you own one of each they're like chalk and cheese (copied from my other post in id section):

Pachanoi Tip:

Pachanoi Spination (note the skin texture!):

Scopulicola areole layout:

Closeup socp spine, again note skin texture (unfortunately this guy is far too tall for me to get a good pic of the growing tip at the moment!):

Some more points:

Scops commonly have 5 or 6 ribs, with occasional 4's and very rare 7's.

Pachanoi commonly has 6-8 ribs with occasional 5's and 9's and very rare 4's.

Scops have rough skin (as can be seen in bits pic) which you can rub your finger on and its rough. They also do not produce the blue 'frosting' (glaucous) that can be rubbed off.

Pachanoi has smooth skin and if you rub your finger on it you could imagine it making a 'squeaky' sound. There may also be a blue or whitish frosting that rubs off which scops do not have.

Scops do not pup as readily as pachanoi.

Scops are really chunky and large diameter compared to many pachanoi.

Scops are slower growing than pachanoi.

Scops have a tendency to do weird stuff with their ribs. For instance you may see a part where it has added or deleted a rib (or both at the same time), or it has grown a new rib and then decided it actually doesn't want that rib resulting in a little mini-rib part way up the plant. Pachs are much more stable with their rib count with the exception of young pups which often have a change in rib numbers as they grow.
