Everyones anatomy and diet are somewhat unique, and as a result, their outputs will vary. The amount of fiber you consume can have a huge impact on how 'sticky' and subject to streaking your deposits are as can how hydrated you are. So, bottom line, your results may vary, but the majority of people don't have an issue.
I've not studied whether Toto's seat positions a person at a different location than others...that's eminently possible, but I don't know. I do know that it tends to be fairly deeply dished, and most people will only find one comfortable position, whereas a flatter one, a person could shift moderately forward or backward, and that could make a difference. That's one aspect of the Toto seats some people don't like...I find mine comfortable. Another reason there are choices in life - one thing rarely works for everyone for one reason or another.
