I've never had a toilet with Sanagloss, so I can't comment on that. Some people here seem to love it.
I do, however, have an Ultramax and a Drake, and I rarely get anything sticking to the bowl. The flush action is so fast, there isn't time for anything to stick. My old toilet would swirl everything around a few times and cause all kinds of problems. I haven't had a problem with the Totos in that respect (or any repspect) at all.
