You can use templates that someone else made and change them to suit you, that level of collaboration is excellent and helps me a lot to find diverse ways of presenting information.

The aesthetically pleasing layout from the audience viewpoint is what I like best.

Love creating a Prezi presentation as an alternative other than Powerpoint. It is an interactive and impressive tool for your audience. My audience is usually more engaged, and there are so many options and customizations I can play with to connect it to my presentation.
