Ranked in these QuestionsQuestion Ranking
Pro Supports tileset addition and extraction
Pro Scriptable using Lua
GrafX2 is scriptable using the Lua language, which can be used to automate tasks and add new functionality to it. The script library features advanced color reduction and enhancement tools, palette analysis, and much more.
Pro Free, open source, and cross-platform
GrafX2 is totally free to use, copy, and modify. It's available on Windows, Linux, Mac OS X, Haiku, AROS, MorphOS, SkyOS, Syllable, Mint, and a few more systems. Basically anything is supported by the SDL library.
Pro Very large number of tools and effects
Pro Supports animations
The program has a basic support for animation using frames in newer versions. Graphics can be cloned and copied between frames and changed slightly.

Pro Supports many file formats
GrafX2 supports many file formats, including the popular gif and png, but also importing and exporting from deluxe paint, degas elite, and various other editors using custom formats.
Pro Has a great palette tool
You can create gradients from one color to another, work in either RGB or HSL color space, save and load palettes, sort and organize palettes, and even work on "color cycling" images.
Pro Has a customizable UI with themes support
Theme UI style can easily be changed from settings including buttons and colors.
Pro Palette Color Cycling
GraphX2 being based on older 256 bitmap software has inherited some tricks that modern pixel editors do not have . One of them being the ability to cycle color palette and produce animations and effects with it.
Pro Quick and easy keyframe animation
Animation is calculated as movement paths between keyframes, and creating a keyframe requires only placing sprites and assigning a time index.
Pro Easy configuration of character maps
Spriter makes it easy to change the character skin, and the animations persists.
Pro Free upgrade to Spriter Pro 2
Free upgrade to Spriter Pro 2.
Price is a lot less than Spine for the pro version and goes on sales often.
Pro Steam intergration
Steam integration is great for updates and tracking hour progression with the software.
Con Sluggish performance with Unity Runtime
Con This version will never have 3D mess support
Yes, there will be a free upgrade to Spriter Pro 2 which will have this feature, but it will be years until that program is read as mentioned on the official site. The issue being that they do not have a way to program this in their current exported runtime. So, for not both Dragon Bones, Spine, and Blender, are the best options it seems for 3D mesh support which really adds something to game animations.
Con No hotkeys for stepping through animation frames
Stepping the animation forward and backward requires using the mouse, extremely inconvenient when fine-tuning motion paths.
Con No curved paths
All motion paths are linear. Curves have to be simulated by hand-placing additional keyframes.
