@dales_fragoso at liblab we create SDKs that look like your developers built them rather than something generated by a machine. We also allow you to customize the SDKs with your own code (or through our customization options). As a commercial product, liblab offers support and advisory services, ranging from API best practices all the way to implementing the correct structure in your spec. liblab also provide a management platform to see all the code generation activity within your org. Simply put, you don't get a tool like you would with the open source option, you get a solution with liblab.
Also, when you use our product you get to interact with our awesome team, which I think is a bonus by itself!
