"Concision" vs. "conciseness" [closed]

See this Etymonline entry that distinguishes these two words. It says that concision is a more recent "literary critic's word" & conciseness is probably more familiar to the average Anglophone. Use the one that better suits your audience. In an academic paper, use concision; in more informal prose, use conciseness. Or else be consistent & always use the one you prefer. It probably won't matter to your readers.

Conciseness used to be overwhelmingly preferred, but now they're running pretty much neck and neck.

Depending on the context, it might better to avoid the noun and use the adjective concise instead.

Both words mean “the quality of being concise.” Conciseness is used more often in English writing, overwhelmingly so until recently.
