Kohler 1 piece Memoirs and Portrait toilets

Im deciding between the Kohler 1 piece Memoirs or Portrait toilets?? The Portrait has a pull-up flush actuator in the center of the tank top.

Does this pull-up knob perform the same as the standard flush handle?

Any input on Kohler ingenium flush system??

I love the 1 piece look. Are there any disadvantages??

I like one-piece designs better, but then some of it is in the eye of the beholder.

Kohler ingenium flush system? It's a 2" flush valve with siphon jet.
If that sounds about 100 years old, don't worry, it's now got a nice name for it.
Performance for the 2" flush valve that Kohler uses ranges from a low of 125 grams and a high of 500 grams.
MaP testing on the Memoirs was 125 grams.

I've have not heard much good about the ones you're asking about, but then they do work for some. So much depends on your habits. If performance is needed, you could find better.
