Ranked in these QuestionsQuestion Ranking
Pro Lifetime updates
Pay once, get updates forever.
Pro Compatible with Photoshop PSD files
Affinity Photo can import and export .psd files.
Pro Interface will be familiar to those coming from Photoshop
The interface, especially the Photo persona, is laid out in way that's very similar to Photoshop - a panel for icons for tools on the left, a panel for information and settings on the right.
Pro Supports layer styles
Layer styles allow non-destructively applying effects to a layer.
Pro Personas allow separation of concerns
At a high level the interface is organized into broad groups of tools called Personas. Personas like Photo for in-depth image manipulation, Liquify for warping the image, Develop for basic RAW photo development and Export for exporting. Each persona displays only those tools that are needed for that task.
Pro Great performance
Uses the GPU extensively for fast speed on any platform.
Pro Powerful effects
Dozens of visual effects available. All run extremely fast with live previews
Pro Non-destructive adjustment layers
extensive adjustment layers are non-destructive.
Paint.net provides a streamlined but effective core tool set. Support for advanced and niche features is provided through modular plugins, allowing the user to install only what's needed.
Pro Free software
There is no charge for this software; but donations are welcomed.
Pro Easy to learn and use
Unlike most photo editing software, Paint.NET is simple to learn and easy to use. This means less time is spent learning the in's and out's of Paint.NET and more time on photo editing. For those who only edit photos sporadically and don't have time to invest in learning complicated tools for editing, Paint.Net will suit your needs.
Pro Plugins allow extra functionality
Plugins can be made by anyone in the community, and are offered for download on the forum. They extend the capabilities of Paint.NET to cover most tasks.
Pro Active and friendly community
The forums are filled with tutorials, as well as people who are friendly and eager to help.
Pro HiDPI support
Paint.NET supports fully HiDPI displays, with no scaling problems.
Pro Actively developed
The project is active and being continually expanded and refined.
Con Limited selection of plugins
Plugin support was only recently added to AP and not many plugins have been created for the program so far.
Con Can not import gimp or krita files
Free alternatives like gimp (and krita) are sort of "go to" apps i can allways install and use for simple image editing or graphics on any computer. I find affinitys support for photoshop is great, but having support also for opening and editing gimp and krita would make the versatility and use of this program absolutely superb.
Con Only available on Windows
Paint.NET is only available on Windows.
Con No project-based interface
You can only edit a single image at a time in Paint.NET. For example, in other tools you can open 5 or a 100 images at the same time, and stack those windows in all directions.
Furthermore, when you are editing in Paint.NET you can only "view" a single image at a time, even though you can have multiple images open. This limits your zooming ability, as the image will go fullscreen quite quickly, and hide parts of it behind the floating toolbars which can not be embedded anywhere on the screen.
