Has anyone purposely "undazzled" their pitches/presentations/sales calls lately? I will not promote.

This is for both in-person and recorded demos/pitches. It's incredibly easy now to make a crazy 5d lightshow of a pitchdeck using AI. I'm tempted to build a deck that is just above old-school-powerpoint level of dazzle just to see how it hits. I've also purposely stopped using any buzzwords or even polishing my speaking style to be perfect. I think I come across as way more genuine and trustworthy if I'm speaking from the heart and avoiding the razzle dazzle. I don't even care about stumbling on words or saying "I don't know" if it's answering a question I don't have the answer for right away. Making shit up on the spot is an easy tell. Maybe it varies from industry to industry. Interested in thoughts.
