Aviary is a great product, but their primary service is different from what I'm building. They focus on client side applications similar to what Instagram provides (filters) in their mobile app. 6px is a solution for processing images -- one off or in batch. Think Instagam's backend processing infrastructure, available to all developers. If you have an image oriented application, you can offload the processing to 6px and don't have to worry about scaling as your application picks up traffic.
