LaTeX is great for when you need to focus on your content and don't have much time to spend on the presentation. However, once the presentation is the entire point, LaTeX is not the right tool.
For me personally, my slides improved significantly when I started using Latex. Imo Latex forces you to give clean, concise presentations. If there is content that takes a lot of fiddling, your presentation is probably overloaded with things that won't reach the audience anyway.

Well, except if you like boring posters.
