How Much Does Your Sampler Really Matter?

Its a question I've asked myself many times, and in this pictorial I will let you make up your own mind.

This is based on "realistic" or at least semi-realistic images.

Not sure if my testing methodology is sound or not but here are all of the A1111 samplers i have

Im going to group sampler images together based on their overall output, to really see the difference in them you really need to view them in slide show on top of one another, but this is the best I can do on here.

In each image, Sampler, Completion Time, and Iterations Per Second are Listed.

*For some Samplers the times or IT/s may see a bit off. This is because some samplers change the amount of steps based on their design.
