Is this good advice?

Does the traditional usage, hallowed by prescriptive grammars and style guides, improve the clarity or precision of the sentence? If so, use the traditional usage.

Does the colloquial usage add clarity or precision to the more traditional version? — if so, use the colloquial one, rules be damned.

Unless perhaps the writing is extremely formal, I would consider that to be good advice, yes.
