@mammothguy54 , good choice. The Sussurro is more accurate and tracks better. I have not looked at the Umami Red Stylus but I have only seen one stylus that was polished better than the Soundmith (the Sussurro and Voice use the exact same stylus and cantilever) and that is on a $10,000 cartridge. The picture about is of very high magnification but look at the stylus it is perfectly clear of imperfections. That is not what you commonly get. Some styluses are actually black.
What I am seeing is that the more expensive cartridges have intentionally selected styluses and appear to be polished better. Soundsmith seems to have used it's best stylus down to the $3000 level for sure and maybe even further down the line.
I will start more threads on the topic of styluses after I gather enough photos to show everyone. I will post them so everyone can see for themselves.
