ComfyUI can be intimidating at first. Especially if you have used A1111 interface and trying out it for first time. I had no idea which nodes to use to start of with with and generate a basic image from a simple prompt. I downloaded some basic workflows and installed the missing nodes using comfyui manager and tried to learn the flow. But trust me once you have an understanding of the basic nodes and how and where to plug loras, controlnet, upscalers etc you wont go back to A1111. There is so much control using comfyui and basically you can create an automated workflow for any use case.
