aquia I vs Aquia II - Functionality

[emppoint]

HI,
I am considering an aquia toilet due to the space constraints of my bathroom layout. I have seen the parts differences listed... but from an everyday use standpoint what are the differences pro/con between the aquia I and II

thank you

In the Seattle area, once the ones are gone, they are gone.
We will be selling the twos only.

The two is a little easier to install and is a bit quieter.
They both work fine.
