Difference between CST746CEMG and a Drake II?

[MyNameIsNebula]

Hello!

Looking to upgrade my toilet to a Toto. I've narrowed it down to the "new" Drake CST746 series that has dual flush. Either 1.6 and 0.8 or 1.28 and 0.8. the price on these seem to be well under $300 each. They use Dynamax tornado flush and are CEFIONTECT coated. Elongated bowl for sure!

Can someone explain to me what the difference is between these and the Drake II? I think it looks like all Drake IIs are either universal height or ADA height, while the Drake Is can be those, or normal height (I think I want normal height) - and use "Tornado Flush", specifically not Dynamax?

Other than that...why are the Drake IIs over $400?

Are there cheap components in these "new" Drake Is? The bowl looks smaller in the picture..is it?

Thank you!!!

Edit; do they both fit a normal "elongated" toilet seat? I have some nice slow close, easy clean Bemis ones!

Very little water in the bowl. More cleaning is needed.

Here is a II series bowl. The CST454CEMFG bowl will have water in the bowl similar to this.
Much easier to keep clean.

It may be that the Dynamax Tornado bowl is easier to make, since there is no siphon jet.

Note that there are versions before the Drake II that did not have Dynamax, and used the siphon jet. Make sure the thing you are looking at says Dynamax if that is what you want.

EDIT: Dynamax appear to not flush well. Check for more info.

Thank you!

Good discussion there, although I wish there were some more reviews online, with these being fairly new. The dual flush seems great to me, but I'm hoping that it isn't just another point where parts can frequently break or fail.

If the bowls are the same size, I think I'll go with the new Drake 1 dual flush, is there some way to confirm? The TOTO diagrams do not list bowl size, and it almost seems like the Drake I elongated is...elongated in the front, but not a full oval bowl? Seems smaller than the Drake II, from the description and diagram, but hard to confirm.

CST746 has very little water in the bowl. More cleaning is needed on these bowls.
