How much should we incorporate stylization and how much should we  not?

Puritan preaching, though profound in its content, was popular in its style. Thomas Goodwin complained in other preacher of ‘the eminentist farrago of all sorts of flowers of wit that are found in any of the Fathers, poets, histories, similitudes, or whatever has the elegancy of wit in it’. But the Puritans eschewed ‘witty’ and clever preaching, which exalts the preacher rather than the Saviour. Weighty matters demand plain words. In Ryle’s autobiographical words, they ‘crucified their style’, and preached with dignified simplicity.  Source is here.

God has wired us how yet also gives us the ability to crucify some elements (humor, seriousness, etc). Love to hear your thoughts on how much of our personality should make it into our messages and/or worship leading. Thoughts?
