When comparing GameSalad vs Blender, the Slant community recommends Blender for most people. In the question“What are the best game engines for beginners and non-programmers?” Blender is ranked 10th while GameSalad is ranked 29th. The most important reason people chose Blender is:
Blender is licensed under the GPL. Some Blender modules such as the Cycles rendering engine are licensed under the Apache 2.0 license.

Pros

Pro Cross-Platform
Pro No-code editor
Pro Has a Windows(.exe) version on par with Mac
The Windows version is now upto date with all the features of its Mac sibling.
Pro Multiple publishing platforms
Can create and publish games for iOS, Macintosh desktop and laptop computers, Android, Kindle, Amazon FireTV and FireTV Stick, Windows 8 and Tizen devices.
Pro Gamepad support
Gamepad support is available as of 0.13.3.
Pro Free standalone viewer app allows instant, live mobile device testing
The GameSalad Viewer is a free app available for iOS, Android and Kindle. Once installed on your mobile devices, you can deploy and test your GameSalad games live on any mobile device running the Viewer that is on the same local network as your dev computer.
This even allows Windows users to test their games on iOS devices without a Mac device and without any complicated code signing or provisioning profiles.
And, you can even take your games with you -- once loaded onto your mobile device, a history option caches recent games on your device without any connection to the dev computer.
Pro Allows you to focus on the logic rather than code
Since the user mainly uses menu options there is very little code needed to be keyed in. This makes the code very easy to read and understand.
Hence there are many help videos on youtube
Pro Extensive community of seasoned professionals for support
Extensive community of seasoned professionals in all disciplines (graphics, game design, animation, physics, music, video production, marketing, etc.) producing tutorials, videos, publishing tips, free templates and who are willing to answer forum questions and help newcomers.
Pro Powerful expression editor and functions
Allows you to create expressions on par with LUA (it's back end-language).
Pro Custom collision shapes with JSON support
Allows you to import JSON data for custom collision shapes to use with Gamesalad's implementation of Box2d physics.
Pro Easy to publish
Software prepares your app so you can just send it to Apple. All my games are reviewed with no problems.

Pro Drag and drop editor
The drag and drop editor makes GameSalad very easy to use, no programming experience needed.
Pro Great engine
Very quick to learn and great for making games. Community is very open and helpful.


Pro Free and open source
Blender is licensed under the GPL. Some Blender modules such as the Cycles rendering engine are licensed under the Apache 2.0 license.

Pro Wide import and export format support
Support lots of modern 3D formats including DAE and FBX - ideal for game developers.
Pro Has a powerful rendering engine
Blender runs the Cycles path tracing engine under the hood. Cycles is a very powerful rendering engine capable of full path tracing (light fall off, caustics, volumetrics). It is mostly compatible with OpenCL and CUDA rendering, and is implementing mycropolygon displacement features. The upcoming release has a viewport engine called EEVEE whereby you can see and interact with your work in render mode in real time!

Pro Python extensibility
Blender embeds Python 3, which can be used to write add-ons, tools, extend the interface, rig characters and automate tasks.

Pro Powerful animation suite
Blender provides a full rigging system, and automates animation by interpolating between keyframe positions.
Pro Supports both low-poly and hi-poly modeling

Pro Regular release schedule
Releases are made every ~3 months.
Pro Sculpting and 3D painting features
Although Blender's 3d painting and sculpting tools (mostly painting) are not at par with specialized software like Substance Painter, ZBrush, or Mari, it is more than capable of getting most jobs done if the user takes the time to learn and understand it.

Pro Includes video editing & compositing tools
Blender's node-based compositor has comprehensive video sequencing and post-processing features.
Pro Node based modeling support
Pro Keyboard shortcuts
Good keyboard shortcuts for everything. Keep your left hand on the keyboard and your right hand on the mouse.
Pro Very useful for a freelancer
It offers a round solution (it covers many areas and professional fields) for a freelancer, for free, constantly updated, very polished, and allowing high quality results that clients do require. After some learning, it becomes very useful for professional work.
Pro Has a large community
There's a huge community to help you get started immediately.
Pro Coherent and streamlined workflow / internal use logic
The trick with Blender is to get used to its usage philosophy, as it keeps consistent through all the application. Once you get it, every feature or addition is learnt naturally, almost effortlessly.
Pro Very versatile
You don't have to switch between software when you want to do different things. Because modeling, sculpting, composting, video editing etc can all be done in blender.
Pro Generative geometry using nodes
Cons
Con Bad editor
There is no scene zoom, search boxes, or snap to grid. There is also no ability to focus view on the actor or use folders for file structure.
Con Expensive compare with others
There is no free version any more and it is very expensive compared with other engines.
Con Poor editor performance
Especially when you're working on a big project.
Con No scripting language or SDK
If a needed behavior is not supplied by GameSalad, there's no way to add it.
Con Product is suffering - Lacking company leadership and no voice from corporate
Some customers are currently in a holding pattern from the lack of support and messaging from GS corporate. GS is currently unstable and developers are waiting for another update that has been going on from 2015.
No word or message from GS corporate about timeframes or deliverables.
You can read the ongoing discussion here.
Con Product is in Limbo - company is lacking developers
Con Doesn't support Windows platform (*.exe)
Doesn't support Windows platform (*.exe)
Con Too many possibilities, no unified workflow
The operations are not optimized enough for specific tasks.
Con The physics engine is a bit lagging behind, especially the destruction physics
Con Difficult learning curve
Blender has a history of being unintuitive, but the 2.8 overhaul made the program far easier for beginners to pick up, and changes continue to be made to further improve the experience. However, there is still a learning curve.
Con Not good for Industrial Design because it uses average vertex normals
You can not create a hard surface with a radius continuity degree along a surface using a specific radius value.
Con Vertex normal issues on edges after boolean operations.
After creating a simple boolean operation the vertex normals are broken. A lot of work to fix the issue and you loos surface continuity.
Con Bad vertex normal after boolean operations
Does not handle well polygon intersections. And need tweaking by hand points or adding average vertex normals via modifiers.
Con Does not handle NURBs
Is not capable of real hard surface for industrial design because is not able to reproduce surface continuity degree as a NURBs does and average vertex normal destroy surface radius.
Con Poor particle system
The Blender particle system can at times be a little limiting and finicky (and buggy) to get working. Even if it can get most straight forward jobs done, it is far from the most advanced system, and could benefit largely from advancements.
