Before I built my muff, I researched and listened to clips of all the variants I could and decided I liked the Triangle. So that's what I built, and it turned out as I liked, and satisfies any muff need I have (mine has a mid knob). I also have a Acid Rain, which is a slightly different take without its clipping diodes. I haven't gone down the rabbit hole of all the others though, as these two have got me covered.
