"You will have noticed that the slope-based lines above "wiggle" more. This is true, and might be considered one of the drawbacks of the algorithm. However, the fact that BRR lines are more temporally stable can also conceivably be useful in some applications." For nearly all applications, better quality for trivial cost is preferred. The "instability" of classic lies is almost always a benefit -- it provides a very cheap form of motion blur / time-dimension dithering anti-aliasing that hides the ugly pixel aliasing of stable lines. BRR is only better when generating extremely complicated demos, where hyperoptimization matters more than control over the image. For most applications, drawing what the developer/user wants is more important than more complex but arbitrary effects.
