I also created an account just to weigh in here. One would think this is a campaign orchestrated by Toto competitors, but it’s not.
Just installed a Toto Drake CST776 (I think). Definite splashback, but learning to adjust my position resolved it. The Toto bowl and seat are definitely designed differently than the toilets I’ve used before, less room up front, more sloped, and the seat that came with it seats you up further. I’ll try ordering the SS154#01 seat to see if it makes a difference.
My guess is most folks don’t have this issue or they adjust how they use it to minimize.
