I'm not sure. I have little familiarity with Ruby, writing my code mostly in Python. But on uniformity, consistency, and ubiquity, at least when compared to Python, I think Smalltalk has the advantage of being implemented in itself, all the way down to the VM. So, once you learn the the language, it's straightforward to study the implementation details of anything inside the system image. On the other hand, when deep-diving in Python, its hard to avoid smashing your head against the C bedrock underneath, as many parts of the language and important modules are just wrappers around C code. I think Ruby may be similar to Python here.
