Every list of best practices, for every LISP, agrees that macro use is generally a "use rarely" thing. And Clojure seems to have developed idioms around simplicity.

Scala, on the other hand, has wildly diverging sets of best practices. The feature set is huge, attempting to appeal to pure functional programmers in their academic ivory towers, and the grizzled Java developers who believe OOP is the one true way, and everyone in between.

It's easy to -say- that there are 5000 ways to do the same thing in a LISP, and only 5-10 ways to do the same thing in Scala (both statements being hyperbolic, presumably; there are infinitely many ways of doing each, after all), the meaningful variations you are likely to see in the wild are far, far lower in Clojure than Scala. And will likely be based on different understandings/expressions of the problem, rather than on different language subsets that the author prefers.
