For many, the Ultimate (Blue flapper PowerGravity) is fine. The $40 for the Ultramax depends on who is using the fixtures. I find that some customers with young kids, the paper users, tend to opt up to the G-Max.
I sell more of the elongated bowls for many reasons.
It doesn't make any sense for men to use round bowls.
And there's a little more area to catch those misses.

They cost the plumber and the builder less.
One of my big sellers is the MS854114SG with the Sanagloss
I would say the most deluxe, are the Soiree and the Gunivere
