This custom node for ComfyUI allows you to test combinations of samplers and schedulers. It generates a batch of generated images(latents), as well as RGB images, each one annotated with the specific combination used, performance timing, and several image quality metrics (Laplacian Variance, Gradient Mean, FFT-based sharpness) for our internal usage, but kept as they could may be useful for others to.
