Not just compared to the other surfaces in a restroom. I believe keyboards and phones both lost to toilet seats in that comparison too.

It's probably bad form to bring this type of comment over from reddit but in this case I can't help myself.

Look, as long as you don’t hover-squat or use other techniqies that make it more dirty, you can autoclave the toilet before using it for all I care, so long as that means you actually sit down. I hate seeing poop stains on the rim. That said I will usually sit down without a buffer.

There is something to be said for using squat toilets instead of sitting toilets in public bathrooms, so long as there are properly cleaned sitting toilets for the elderly and disabled (I have seen some shocking disabled public bathrooms over the years)
