Comparison slides in PowerPoint can help to show a comparison between different products and services to an audience. Comparison slides are often being used to compare different alternatives, regardless of the industry and presentation purpose. For example, a SaaS solution or business presentation and pitch deck on a SaaS product can include a comparison slide to compare the different plans available in the Plans & Pricing page. Alternatively, a presentation on an Investment plan can use a comparison slide to compare different investment strategies and options and help the audience to choose between them.

A comparison diagram is a type of diagram that helps to compare different concepts easily. It can be a 1-1 comparison, which will help to compare one item versus another one, or it can be a multi comparison slide where more than 2 concepts, elements or ideas are being compared.

A comparison chart in PowerPoint can be created in multiple ways, for example using PowerPoint shapes or even tables. Often, comparison charts are visually represented in different columns with titles at the top of the chart (where the Product X or Service X is being displayed) and then listing each of the features one by one.

One of the most basic examples of comparison can be found in online services and SaaS products when comparing different plans available. E-commerce websites and review sites also provide comparisons between different products, listing each of the features available on each product plus the price.
