I think short bullet points are great. That way the audience can take them in quickly (I highlight one at a time to prevent them from reading ahead/behind) without being distracted for more than a fraction of a second. It also helps people to see how many items are being discussed (e.g., "there are three reasons that language X is better than language Y"). For me at least, that makes it easier to remember the reasons, since it functions as a checksum.

Do you mean that full paragraph is better? Strong disagree if so.

Perhaps not full paragraphs, but the phrase-style nature of bullet points has never really helped me understand the material. If there must be text, I would rather see complete sentences on a presentation.

I've used the assertion-evidence framework[0] for presentations[1] before, where the idea is to have a complete sentence at the top of your slide, with images below that illustrate your point.
