I appears you have been doing your homework and are looking for assurance that a Toto would be the best choice. About all I can do is reinforce what you have already read. All models of Toto toilets are superior products, so price and style are the major considerations. A basic low flow toilet fact to realize is that none of them (any brand) will have as good a bowl wash as the old water hogs. That said, few people have a real problem with this. An occasional streak, but not a daily problem. There seems to be a consensus that those with a problem with bowl wash may need to improve their diets. My personal experience is a brush kept handy with quickly and easily take care of the infrequent streak. I do not have Sanigloss, but that would be a good option to consider. Pressure assists are to me a gimmick some makers use to try to make poorly designed toilets work. There are at least two real problems with them. First, the powerful blast of water tends to shred toilet paper and these small shreds to not completely flush out. So while the "big stuff" may be gone, there is cloud of these fine particles of paper floating in the bowl. Second concern is that since the system works with this pressurized tank, sooner or later the tank will fail. Repairs to these often are as much a a whole new toilet. Toto has developed a flush that uses what they call a double cyclone and is on some models, but these are not on Drakes or lower priced units. Reports are this double cyclone rinse works very well, but my experience with my Dartmouth and Drake has not convinced me that I would see any difference since I have no bad experiences with bowl wash after 2 plus years. The only clogging ever reported on the forum has been when an object that should not be put in the toilet gets crosswise in the trap. Many of us don't even own a plunger. The final thought I have is that it seems that the hardest part of buy a Toto is to select the model. The good part of that is, no matter which one you choose, you will have an excellent toilet.
