If you are buying a new toilet, and not a 80's or older second hand toilet,
Then the best of the bunch are the Toto Soiree and Gunivere.
The bowls have Sanagloss, and the rinse is the double cyclone.
After that, I like the other products with Sanagloss in the bowl,
Those would be CST744SG Drake, MS854114SG Ultramax, MS874114SG Carlyle, CST764SG Vespin
