Latency, support, specifications. The EC2 GPU nodes have less, slower, memory, graphics cards with half the performance and a third of the memory, and less drive space. Additionally, said compute resources are not next to you, which means certain things, like deep learning combined with AR are not possible. If you're just doing number crunching, you may be fine with EC2 instances, but any sort of realtime development, you probably want a supported platform right next to you.
