Why do you prefer Gamma over other AI tools for creating presentations?

The speaker's preference is Gamma because it looks more polished and refined, having used it for a couple of years. Their view is that while many things could be replaced with general AI tools, a specialized tool like Gamma produces a better quality result for presentations specifically — comparing it to the difference between an actual taco restaurant and getting tacos from Jack in the Box: both offer the product, but the quality differs.
