I'm curious about the cliché or obscure superlatives with no constraints other than the scope of impact; could be positive or negative in some contexts.
As a TeX hobbyist, I would argue that they serve slightly different purposes. Plain TeX is for typography, the workflow is that of low level control where your human judgement is needed for interventions and decisions. LaTeX serves a different purpose, it aides the author of a text to focus on the content while abstracting away the underlying inherent problems in fitting letters on a page. TeX is small, difficult, but simple. LaTeX is huge, with 30 years of abstractions built on top of abstractions, until nowadays few people know how to actually deal with an overfull or underfull hbox the right way.
