When comparing Genome2D vs WiMi5, the Slant community recommends Genome2D for most people. In the question“What are the best 2D game engines?” Genome2D is ranked 47th while WiMi5 is ranked 70th. The most important reason people chose Genome2D is:
It's the fastest gpu-based framework out there for flash. It's beautifully optimised. It has very low rendering latency, low level OpenGL calls that other tech simply cannot do (ie Unity) due to Stage3D, and thus can render a lot more data quicker

Pros

Pro Lightning fast
It's the fastest gpu-based framework out there for flash. It's beautifully optimised. It has very low rendering latency, low level OpenGL calls that other tech simply cannot do (ie Unity) due to Stage3D, and thus can render a lot more data quicker
Pro Cross-platform mobile, desktop and web
Supports Windows, Mac OS X, Linux, iOS, Android, Web and native Flash.
And with the HTML5 export, it also potentially supports development for the Wii U :)
Pro Haxe!
Haxe is a strictly typed programming language that saves development time but still compiles high performance executables, and can build for tons of different platforms (flash, c++, html5, java, c#, etc.)
Pro Access to direct draw features
Has access to direct draw features so you can make you own rendering structures (scene graphs etc).
Pro Automatic dynamic batching
Automatically batch geometries with dynamic batching techniques (by using constant buffers).
Pro Component based architecture
Pro Versatile flow diagram script model
WiMi5 integrates a powerful visual scripting solution based on Blackboxes that allows you to create the logic flow of the game. You don't have to code (if you don't want) but you can also do it. WiMi5's actions and behaviors resemble flowcharts where each box represents a function or value, with connections between them representing program flow. This provides a better at-a-glance indication of game logic than a simple list of events, and makes complex behaviors easier to accomplish.
Pro Integrated servers
WiMi5 provides integrated back-end services, with tools available to save game session data, manage rankings, etc.
Pro Free development
The WiMi5 platform is free to use, supported by post-publication royalties.
Pro Built in monetisation tools
WiMi5 provides features to manage in-app purchases and micropayments. Virtual Goods management is integrated into the Logic Editor.
Pro Publication partnerships
WiMi5 maintains partnerships allowing simultaneous publication to a number of Web and mobile stores, all managed through the WiMi5 platform.
Games can also be downloaded and publish it wherever you want: in your own server or with your own partners. Just check the Download feature in the settings of your game.
Cons
Con Lacks documentation
The API documentation is minimal, there's not many tutorials and the ones that are there are very small and only cover the basics. If you want to learn how to properly use it, you have to ask the community or read the source code and figure it out.
Con Not too many games to showcase it
Con Slow development rate
Con 30% royalties
For filling the engine, publisher, and back-end service roles, WiMi5 takes 30% of game revenues.
